PTGui Pro Changelog

What's new in PTGui Pro 13.0 Beta 6

Apr 20, 2024

Fixed: Windows: the application list in the Patch Panel in the detail viewer showed the .jpg-capable applications even when another file type was chosen.
Fixed: PTGui could crash, or give an 'invalid vector subscript' or 'assertion failed' error.
Fixed: Lines or other small artifacts could occasionally be visible in the panorama if GPU acceleration was enabled
Fixed: Mac: it was possible to drag the window upwards behind the menu bar, with no way to move it down again because the title bar is then obstructed by the menu bar.
Fixed: GPS coordinates in the XMP metadata in the output were corrupt. As a result, GPS coordinates were missing in generated .psd and .psb files.
Fixed: When linking HDR brackets, PTGui would switch to Advanced mode but this was unnecessary
PTGui now recognizes the Olympus M.Zuiko Digital ED 8mm 1:1.8 from the EXIF data
PTGui can now load Phase One .IIQ raw files
Added lens profile for AstrHori 12mm 2.8 Fisheye

New in PTGui Pro 13.0 Beta 5 (Apr 2, 2024)

New in PTGui Pro 13.0 Beta 4 (Mar 17, 2024)

New in PTGui Pro 13.0 Beta 3 (Mar 14, 2024)

The Detail Viewer now has a side bar like the panorama editor. There's a 'View' section which shows and edits the current viewing angles.
New Snapshot tool in the Detail Viewer. This saves the current view to an image. Rather than a screenshot, this actually renders the current view at full resolution.
PTGui now avoids creating control points between non-adjacent images. For example if we have 3 images in a row, PTGui will create control points between image 1 & 2 and between 2 & 3, but avoids creating control points between 1 & 3. Especially in case of parallax, this will improve alignment. There's also a new menu option 'Control Points - Remove control points between non-adjacent images'.
If Exposure Fusion is not enabled, the default HDR workflow has been changed to 'Merge to HDR first, then blend', because this results in much faster rendering of the panorama and requires less memory. Blend planes cannot be generated in this mode though. For exposure fusion panoramas, blend planes are still enabled by default because this gives better results. The default HDR workflow can be overridden in the Exposure/HDR tab.
PTGui is better able to find control points for back-to-back fisheye images such as those produced by one shot 360 degree cameras. Back-to-back fisheye images overlap in just a narrow ring at the edge of the fisheye circle, and until now PTGui had difficulty finding control points.
The default spacing between items in the user interface has been increased slightly, for better readability.
Keyboard shortcuts have been added for navigating between the tabs in the main window (see menu View -> Go to Tab).
By default PTGui will limit GPU memory usage (video RAM) to 2 GB. This can be changed in the Options/Preferences window. Generally, using more than 2GB of video ram does not improve stitching time and this change will allow other applications to share the GPU while PTGui is running (if it has more than 2GB RAM).
PTGui no longer always attempts to use the source color profile for the output. Instead there's now an 'Automatic' setting, where it will pick a suitable color space. Color profiles created by scanner or camera calibration tools are often input-only, and attempting to use this same color space for the output would result in an error. It also avoids the use of LUT color spaces, which are slow to render. PTGui always picks a color space 'better' than those of the source images (i.e. a color space with a wider gamut), so no color information is lost. This is just the new default behavior; a custom color profile can still be chosen for the output.
Separate color profiles can be selected for the LDR and HDR output images. HDR output requires a linear color profile, while for LDR images usually a profile with some gamma curve is used.
White balance adjustment has been moved to a dedicated White Balance panel in the Panorama Editor. Previously this was in the Post Process panel. White balance adjustment affects both the HDR and LDR output, and this separates it from the other adjustments in the Post Processing tab, which only affect the LDR output.
Additional Tint control for adjusting white balance. 'Temperature' adjusts between blue and yellow, 'Tint' between green and magenta.
'As Shot' white balance is replaced by an 'Automatic' setting. In Automatic mode the average color temperature of all source images is calculated, and this is used for the generated panorama. Better results are obtained for source images are taken with automatic white balance. If all images were taken with identical white balance, 'Automatic' will give the same result as 'As Shot'.
A new command line option was added for creating a new project file from a given set of images and optionally a template:
PTGui[.exe] -createproject img1.jpg img2.jpg -output project.pts [-template template.pts]
This creates a project file for the given source images, optionally using a template, but does not stitch it yet. No GUI is shown. The project can be opened in PTGui, or it can be stitched from the command line using the -stitchnogui flag. The -createproject and -stitchnogui flags can even be combined in a single command line, in which case the project is created and stitched in one go:
PTGui[.exe] -createproject img1.jpg img2.jpg -output project.pts -template template.pts -stitchnogui project.pts
PTGui can now read accelerometer and compass data from iPhone images, so the images will be positioned correctly immediately after loading.
New 'Color sampler' tool in Panorama Editor and Detail Viewer. This can be used to adjust the white balance, by clicking on a grey area in the scene. And in the Pro version this allows adjusting the HDR exposure for the selected pixel to a given value. This way it's possible to photograph a grey card with known reflectance and match the HDR exposure to scene light intensity at the location of the grey card.
'Images -> Link HDR Bracketed exposures' now also works even if PTGui wasn't able to detect a repeating exposure sequence. In this case a custom bracket size can be entered.
The Panorama Editor can now preview the true HDR image. Previously it would always show the LDR output, which has curves applied and may be tone mapped. The full dynamic range can be inspected using the Exposure slider in the Display panel in the Panorama Editor.
There's a new 'HDR Exposure' panel in the panorama editor, to adjust the brightness of the generated HDR image. Previously PTGui would always scale the HDR output such that white in the middle exposure (i.e. the 0EV image when bracketing) would be mapped to a brightness of 1.0 in the HDRI. Two additional option have now been added: use the brightest exposure as a reference (so all HDR pixels will lie between 0.0 and 1.0) and Absolute Exposure. In the latter case the HDR exposure is set as an absolute EV offset relative to a 1.0 second exposure at f/1.0 and ISO 100. The HDR exposure can be adjusted interactively using the new Color sampler tool (see above).
For .exr output the Zip and Dwa compression level can be configured in the file format settings window.
Linux: with the -stitchnogui flag PTGui can now run truly headless. Previously a workaround using a VNC server was needed because PTGui required a $DISPLAY even for command line operation.
Linux: if no temporary folders have been configured, PTGui will now by default use /var/tmp for temporary files. Previously it would use /tmp, but on certain Linux distributions this is a ramdisk, which is unsuitable for the (huge) temporary files created by PTGui.
The standard version and the Pro version are now distributed in a single download. After activation the appropriate version is run.
The minimum system requirements had to be updated: PTGui now requires at least macOS 10.15 (Catalina), or Windows 10 build 18362. PTGui for Linux was built against glibc 2.28, which is found in Debian 10.

Automatic optimum seam placement: PTGui Pro 12 will analyze the regions where images overlap, and place the seams in those areas where there is the least difference between the overlapping images. It will attempt to automatically route the seams around moving objects. Also, stitching errors from parallax will be hidden as much as possible.
New 'zero overlap' blending algorithm: blending is done by minimizing the exposure differences at the seams where the images meet. No overlap is needed and pixels outside the seams are not used. Combined with the new optimum seam placement this is able to create absolutely seamless panoramas even of busy scenes with many moving objects. The Multiband blending algorithm used in PTGui 11 and earlier is still available as an option.
New HDR workflow: Merge bracketed images to HDR first, then blend. PTGui Pro 11 and earlier would use the reverse workflow: create blend planes for each exposure level, then merge to HDR. Both options are now possible. The new workflow permits creating HDR panoramas from images taken in automatic exposure mode.
The purpose of linking images has changed: in PTGui Pro 11, linked images would get the same yaw, pitch and roll angles but linking did not otherwise affect HDR processing. In PTGui Pro 12, linking the images will tell PTGui Pro that they belong to the same bracketed set but they don't necessarily have the exact same yaw, pitch and roll. In the 'merge to HDR, then blend' workflow these linked images will be combined to a single HDR source image. In the 'create blend planes' workflow, linking is also necessary because it tells PTGui to place the seam identically for these images. This is important because differently placed seams would cause artifacts when merging the blend planes to HDR. Because linking the images in PTGui 12 no longer automatically gives them the same yaw, pitch and roll angles, a separate 'Link' checkbox has been added to the Image Parameters tab. If unchecked, the bracketed images will have different yaw, pitch and roll angles.
PTGui Pro 12 no longer distinguishes between HDR and non-HDR panoramas, every panorama is HDR. The stitching pipeline uses floating point data internally and any panorama, bracketed or not, can be rendered to HDR formats such as OpenEXR.
New 'Fill Holes' function (PTGui Pro). If enabled, all transparent areas in the panorama will be filled with a smooth color gradient matching the surrounding areas. While not not a true replacement for patching in an external image editor, it works well for example for filling up the blue sky in a drone panorama. Or it can be used as a quick way to cover the nadir of a spherical panorama.
PTGui 12 is fully color managed. Color profiles in source images are recognized and images will be displayed properly on screen. PTGui can transform between color spaces; the desired target color profile can be selected in the Create Panorama tab. Panoramas from RAW source images are no longer limited to sRGB as in PTGui 11.
PTGui has been ported to Linux. The Linux version is fully functional, including support for OpenCL GPU acceleration. A PTGui license is platform independent, so a single license now allows you to run PTGui on all major desktop operating systems. For more information see ptgui.com/linux.
A new Post Processing side bar was added to the Panorama Editor for adjusting the toning curve, white balance and saturation. This is useful in particular when working with RAW source images. The white balance and exposure adjustment sliders have been moved from the Exposure/HDR tab to this Post Process side bar.
PTGui Pro: The behavior of red masks is configurable. Previously red masked areas would always be made transparent in the warped image layers. This would result in a hole in the blended panorama if no other image overlaps. By setting 'Red Masks: Use only to adjust seams', the mask will not result in transparency, it is only used to guide seam placement.
Users of the standard version of PTGui 12 gain access to a number of features previously only available in PTGui Pro: vignetting / exposure correction, Exposure Compensation (for panoramas taken in automatic exposure mode) and most of the Project Settings tab.
The grid (crosshair) in the Panorama Editor can be hidden entirely, by clicking the little triangle below the panorama in the Panorama Editor.
Switching between Exposure Fusion and Tone Mapping (True HDR) can now be done from the panorama editor's side bar (PTGui Pro).
Exposure Fusion is now supported for non-bracketed panoramas as well (PTGui Pro).
Improved metadata support: most XMP metadata is now copied from the first source image to the panorama. This includes for example author, location, copyright info and custom XMP data. Generally all XMP metadata is copied, except for metadata specific to the source image but not applicable to the panorama. For example metadata concerning focal length or the image size is not copied to the panorama, but replaced with appropriate values for the stitched image.
The following additional EXIF tags are now copied from source images to the stitched panoramas: Artist, Copyright, GPS date, GPS time, GPS satellites, camera make/model.
Metadata is now written to Photoshop files as well. Previously this was limited to jpeg and tiff output.
New option 'Masking pushes back seams' in Panorama Editor - Blending tab (PTGui Pro). This controls the location of the seams if optimum seam finding is disabled and masks are placed. If this option is checked, a mask will 'push' the seam away (as was the case in PTGui Pro 11). If disabled, the seam will stay close to the middle of the overlap area even if masks are nearby.
Handling of the camera response curve has been changed. The camera curve must be known for proper vignetting correction and HDR processing, because these operations are done on the actual linear luminance values. Cameras and raw converters generally apply a toning curve to the linear data when creating a tiff/jpg image, to create a more pleasing image. In order to determine the actual luminance of each pixel, PTGui needs to know this curve, so it can 'undo' this adjustment. Previously the camera curve was part of the lens profile, but this was not ideal. First of all, RAW and HDR images contain linear luminance values, so for those images no camera curve is necessary. Secondly, when a project uses multiple lenses on a single camera, a single curve should be used for all images. Therefore the camera curve is now a separate entity in the project. Each project can contain 0 or more camera curves. In the Image Parameters tab, the camera curve for each source image can be selected, or 'Linear' can be selected if the image data is already linear and should not be corrected with a camera curve. PTGui handles this automatically: when loading HDR and RAW source images, their camera curve will be set to Linear. For all other types a default curve will be used. As previously the actual camera curve can be estimated by the 'automatic exposure and color adjustment' process in the Exposure/HDR tab. The optimization requires bracketed images, because the estimate is made by comparing the same pixel in differently exposed images.
PTGui 12 uses a different format for the camera response curve (Exposure/HDR tab). In PTGui 11 the curve was defined against the pixel values as stored in the image file; in PTGui 12 it is defined against the linearized image data (according to the ICC profile). The ICC profile's gamma is no longer included in the camera response curve.
New white balance correction algorithm. Previously there were sliders for adjusting the red/green/blue channels but the results were limited. White balance is now adjusted by setting a Kelvin color temperature for each image (in Image Parameters tab) and a color temperature for the blended panorama. The latter can be adjusted in the Post Process tab. A chromatic adaptation algorithm is used to transform the colors.
The contrast and saturation sliders have been removed from the Tone Mapping section. These are replaced by the new Toning Curve and Saturation adjustments in the Post Process tab, which offer more precise control, and are available also when tone mapping is not used.
Much better image quality when working with raw/dng source images, due to the new toning, white balance and saturation adjustments.
PTGui now reads and writes color profile data in EXR images. Conform the official OpenEXR specification, the color profile is read and written in the 'chromaticities' tag. But note that this is not widely supported. Many other applications (including Photoshop) ignore this entirely, and assume all .exr files have a linear sRgb color profile.
The PTGui Viewer application is now color managed and will display panoramas in the proper colors.
The scale of the vignetting curve (in the Exposure/HDR tab) for circular fisheye lenses has been adjusted. Previously, for all lens types, the right edge of the graphs corresponds to the corner of the source image (after cropping). Because for circular fisheye images the cropping circle only extends to the edges of the cropping area, but not the corners, for circular fisheye images only the leftmost 71% of the vignetting curve was actually applicable. For circular fisheye images the graph is adjusted so that the right hand side corresponds to the edge of the image circle.
New option: Options - General - "Keep multiple panels open in the side bar in the panorama editor"
New setting: Exposure/HDR - Precision: switch the internal processing precision between half float and full float. Full float can be used for images with extremely high dynamic range (for example when including the Sun's luminance). Otherwise half float is sufficient, requires less memory and is the default setting.
New setting: Project Settings - 'Align Images' behavior - perform automatic exposure and color adjustment - but only if alignment was successful.
Automatic exposure and color adjustment is now done by default as part of 'Align Images'.
Preview exposure (as set in the Display panel in the Panorama Editor, and the sliders in Mask/Crop/Control Points) is no longer saved to the project file. Preview exposure is reset to 0 when the project is loaded the next time. This was a common source of confusion because it changes the brightness of the panorama in the Panorama Editor but not the actual stitched panorama.
A warning icon is shown in the Panorama Editor's side bar if the preview exposure is nonzero.
Green indicators are shown in the Tone Mapping, Exposure Fusion and Post Processing side bars in the Panorama Editor when they are active.
DNG files from the Leica M10 Monochrom camera are now supported.
Added Load/Save/Defaults buttons in the Exposure Fusion panel in the Panorama Editor side bar
Exposure and color adjustment settings' window: 'Optimize Exposure' has been renamed to 'Optimize Brightness' which is more correct. The former two options (Full and Fine Tune) have been replaced by a single option 'Enabled'.
Dithering is applied to all 8 bit/channel output files, to solve banding artifacts. 16 bits output is not dithered.
Added support for Sony .ARQ files

Added Load/Save/Defaults buttons in the Exposure Fusion panel in the Panorama Editor side bar
Added Defaults button in the Post Processing panel in the Panorama Editor side bar
Changing the 'Exposure' slider in the panorama editor side bar no longer affects the brightness of the source images in the main window. Only the Preview Exposure slider still works globally in all windows.
'Exposure and color adjustment settings' window: 'Optimize Exposure' has been renamed to 'Optimize Brightness' which is more correct. The former two options (Full and Fine Tune) have been replaced by a single option 'Enabled'.
Fixed: occasional crashing
Fixed: Windows: menu bar was displayed with incorrect font size if the font/icon size in Options was not set to 100%
Fixed: user interface glitches under macOS 11.0 (Big Sur)
Fixed: the results of automatic exposure and color adjustment ('Optimize Now') were not perfect and also unstable. Running Optimize Now! multiple times would give widely different results. This is much improved now. Vignetting correction is much better and HDR artifacts (banding or posterization) should mostly gone now.
Fixed: incorrect warning in the Create Panorama tab about different source ICC profiles, even though all images have the same icc profile
Fixed: incorrect rotation of JPG images from the Ricoh Theta Z1 taken with the DualFisheye plugin
Fixed: HDR TIFF files would always contain an alpha channel, even if 'No alpha channel' was selected in the file format settings.
Fixed: When working with bracketed source images, the merged bracketed images (as displayed in the Crop/Mask/Control Points tab) were displayed overly bright
Fixed: PTGui Viewer on macOS 10.14 and earlier, retina screen: the panorama would only occupy a quarter of the viewer window
Fixed: the exposure fused or tone mapped panorama could be very dark
Fixed: straightening panorama did not work accurately if a nadir or zenith image was included in the project.
Fixed: visible artifacts could appear at the right hand edge of the panorama for certain projects
Fixed: seams could be routed differently in the stitched panorama compared to the preview in the Panorama Editor
Fixed: PTGui could report that the source images had different color profiles, even though they were identical

New in PTGui Pro 12 Beta 8 (Jul 7, 2020)

Preview exposure (as set in the Display panel in the Panorama Editor, and the sliders in Mask/Crop/Control Points) is no longer saved to the project file. Preview exposure is reset to 0 when the project is loaded the next time. This was a common source of confusion because it changes the brightness of the panorama in the Panorama Editor but not the actual stitched panorama.
A warning icon is shown in the Panorama Editor's side bar if the preview exposure is nonzero.
Green indicators are shown in the Tone Mapping, Exposure Fusion and Post Processing side bars in the Panorama Editor when they are active.
Improved Exposure Fusion, the results should now be similar to PTGui 11 again
Improved the algorithm for brightness-dependent saturation (in the Post Process tab), resulting in more naturally looking desaturated highlights.
If the camera curve is optimized (using 'Optimize Now!'), the associated brightness-dependent saturation curve is also optimized. The desaturation of highlights (as done by raw converters) is now better compensated for, resulting in better HDR merging. The optimized curve can be inspected by clicking on the 'pencil' button in the Exposure/HDR tab.
Increased the range for the Expsosure slider in the Post Process tab, from +-2 to +-5 EV.
Many corrections to the French translation, merci beacoup Sébastien!
Holding down the Shift key while launching PTGui will disable OpenCL for the current session. This may be helpful when dealing with GPU driver problems.
Configurable seam finding precision. By default optimum seam finding is done at a lower resolution than the full size, to reduce the time and memory needed. The precision is now configurable in the Blending sidebar in the panorama editor. For certain panoramas increasing the seam finding precision will lead to more seamless panoramas, at the expense of considerably more memory usage and longer stitching time.
Fixed: Possible banding in True HDR panoramas
Fixed: True HDR panoramas could get desaturated highlights. In particular, blue sky could become grey in the HDR panorama.
Fixed: Windows: when editing a text or numeric field on a high DPI screen, the font size would be too large
Fixed: Optimum seam finder would occasionally place small 'islands' of one image inside another image
Fixed: Assertion Failed errors for certain projects
Fixed: HDR merging artifacts when using bracketed sets with a very wide EV range (say, 20EV)
Fixed: When generating control points for bracketed images, control points would be generated between linked images
Fixed: Blending artifacts if images contained partially transparent pixels
Fixed: For certain spherical panoramas, the Detail Viewer would show a vertical seam line at the -180 / +180 boundary
Fixed: When switching to different images in 'Edit Individual Images' in the Panorama Editor, the previously highlighted image would flash briefly.

PTGui now runs on Linux! For details see PTGui 12 for Linux in the PTGui support forum.
Create Panorama tab: PTGui now displays a warning if the source image color profile is not used (e.g. if different color profiles are used, or if raw/dng images are loaded)
Exposure/HDR tab: warning if the camera curve is not actually used in the project. A camera curve must be assigned to one or more images in the Image Parameters tab.
New option: Options - General - "Keep multiple panels open in the side bar in the panorama editor"
New setting: Exposure/HDR - Precision: switch the internal processing precision between half float and full float. Full float can be used for images with extremely high dynamic range (e.g. when including the luminance of the Sun). Otherwise half float is sufficient, requires less memory and is the default setting.

Automatic exposure and color adjustment is now done by default as part of 'Align Images'.
All sliders can be moved slower an more precisely by dragging while holding down the Shift key
All sliders can be moved slower an more precisely by holding down the Shift key together with the left/right arrow key
Post Process - Saturation: right clicking on a slider resets the value to 100%
Windows 10 v1909 (Windows November 2019 update) natively supports dark-themed applications, and PTGui now uses the functionality provided by Windows to create a dark-themed title bar. Previously PTGui had to custom draw the entire window frame in order to get a dark title bar, but this caused a few subtle problems which were difficult to fix.
On Windows 10 v1909 and later: Better High-DPI scaling. The menu bar and title bar are now scaled correctly when using multiple monitors with differen DPI settings.
Fixed: PTGui failed to load images with ACES2065-1 color profile (Asssertion Failed).
Fixed: cropping a cylindrical or equirectangular source image would cause the wrong projection to be used.
Fixed: Automatic exposure and color adjustment could result in extremely non-linear camera curve.

On the outside PTGui 12 may look much like the previous version. But under the hood it features a rewritten stitching engine and a brand new blender!
Optimum seam placement (Pro version only):
PTGui Pro 12 will analyze the regions where images overlap, and place the seams in those areas where the overlapping images are most similar. This means it automatically routes the seams around moving objects. Also, stitching errors from parallax will be hidden as much as possible.
The Panorama Editor and Detail Viewer show a live preview of the seams. Seam placement happens automatically and on the fly, but you can still fully control where the seams should go. As in PTGui 11 the seams can be manipulated using masks: a red mask will exclude an object and move the seam away from that area, while a green mask forces an area to be included in the blended panorama. Masking doesn't have to be done precise at all: usually a green or red dot somewhere on an object is sufficient. The seam finding algorithm will recognize the object's contours and re-route the seam in an optimum path around it.
Zero overlap blending:
Most existing panoramic blenders (including PTGui 11, Enblend, SmartBlend, AutoPano) use a multi-band pyramid blending algorithm. These blending algorithms perform their job in the overlap region of the images and therefore need a certain amount of overlap. In the overlap region a gradual transition is made from the average brightness of one image to the next. Generally these algorithms cannot distinguish between brightness differences caused by exposure variation and brightness differences caused by moving objects. In both cases a gradual brightness change will be created in the overlap region. As a result, moving objects in the overlap region remain visible as faint ghosts or halos. This happens even if the object is nearby the seam, but not actually cut through by it. Also, only the overlap region is available for equalizing brightness differences. If the overlap is narrow and the brightness difference large, the steep change in brightness will remain noticeable.
For PTGui 12 a new blending engine has been built which requires no overlap at all. Brightness differences are distributed across the entire image, such that any differences are minimized where the images meet at the seams. Only the area enclosed by the seams is used, with no risk of ghosting from hidden objects. Combined with optimum seam placement this can create absolutely seamless panoramas even in difficult situations with moving objects.
The new blender is of course capable of blending 360° equirectangular panoramas. As far as we know PTGui is still the only panoramic blender to properly handle the zenith and nadir of fully spherical panoramas. Even images with significant exposure differences are blended very well.
Improved HDR support (Pro version only):
HDR in PTGui 11 is based around 'blend planes': at each EV a complete panorama is stitched and blended. Finally the blend planes are merged to an HDR panorama or combined using Exposure Fusion
To work with the new optimum seam placement, the HDR workflow had to change. A problem with the blend plane approach is that the optimum seam will turn out differently for each blend plane. Around the seams, pixels from different bracketed sets would be merged to HDR and this would result in ugly HDR artifacts. To solve this, PTGui 12 reverses the processing pipeline: now each set of linked images is first merged to HDR and then the HDR images are blended (using optimum seam placement) to an HDR panorama
As an additional benefit, PTGui Pro no longer requires HDR panoramas to be taken in manual exposure (M) mode. This is because each set of bracketed images will be separately merged to HDR. Better yet, the number or sequence of bracketed images doesn't even have to be constant anymore. Just tell PTGui which images are bracketed sets by linking them. It's even possible to generate HDR panoramas from single, non-bracketed images taken in automatic exposure mode
In fact, PTGui Pro 12 no longer distinguishes between HDR and non-HDR panoramas, every panorama is HDR! The stitching pipeline uses floating point data internally and any panorama, bracketed or not, can be rendered to HDR formats such as OpenEXR
Fill Holes (Pro version only):
A handy feature in PTGui Pro 12 is the new 'Fill Holes' function. If enabled, all transparent areas in the panorama will be filled with a smooth color gradient matching the surrounding areas. While not not a true replacement for patching in an external image editor, it works well for example for filling up the blue sky in a drone panorama. Or it can be used as a quick way to cover the nadir of a spherical panorama.
In combination with masking it can be used as a tool to hide or blur objects: simply paint the unwanted contents with a red mask; PTGui will fill the resulting gaps.
Fill Holes can be enabled in the new Blending sidebar in the Panorama Editor.
Color Management:
Long overdue, PTGui 12 is finally fully color managed! While PTGui 11 offers basic support for a color managed workflow, by embedding the proper ICC profile in the stitched panorama, the user interface may display images in the wrong color. PTGui 12 recognizes color profiles in source images and will display them properly on screen.
Other changes:
PTGui Pro: The behavior of red masks is configurable. Previously red masked areas would always be made transparent in the warped image layers. This would result in a hole in the blended panorama if no other image overlaps. By setting 'Red Masks: Use only to adjust seams', the mask will not result in transparency, it is only used to guide seam placement
Users of the standard version of PTGui 12 gain access to a number of features previously only available in PTGui Pro: vignetting / exposure correction, Exposure Compensation (for panoramas taken in automatic exposure mode) and most of the Project Settings tab
PTGui 12 uses a different format for the camera response curve (Exposure/HDR tab). In PTGui 11 the curve is defined against the pixel values as stored in the image file; in PTGui 12 it is defined against the linearized image data (according to the ICC profile)
Some functionality has been removed in PTGui 12:
SmartBlend and Enblend are no longer supported for blending
RAW file support is provided exclusively through LibRaw; support for dcraw has been removed
PTGui no longer supports 32 bit Windows versions

New in PTGui Pro 11.21 (Feb 4, 2020)

New in PTGui Pro 11.20 (Jan 6, 2020)

New in PTGui Pro 11.19 (Nov 19, 2019)

LibRaw (used for decoding of RAW files) has been updated. PTGui can now load Canon .CR3 files and GoPro .GPR files. For details see LibRaw 201910 snapshot.
A 'noise floor' slider has been added in the Exposure/HDR tab. This is used when merging bracketed images (in the True HDR workflow). Use it to remove excessive image noise that might appear in HDR panoramas generated from relatively noisy images (e.g. images taken at high ISO). See the tooltip for the Noise Floor slider for more information.
Performance improvements when using GPU acceleration (40% faster for certain projects on certain hardware).
Fixed: Bug in PTGui web viewer (used by Publish to Website) on an iPad with iPadOS 13: no response from the touchscreen, so navigating the panorama was not possible. All newly created web pages from Publish to Website will use the new version of the viewer. Existing published panoramas can be updated by replacing PTGuiViewer.js with the new version: download the latest PTGuiViewer.js here.
Fixed: If a set of images with a repeating exposure sequence was loaded, and 'This is not an HDR exposure set. Do not enable HDR mode' was selected, the control point generator could still treat it as an HDR exposure sequence and only generate control points between images having the same exposure.
Fixed: OpenCL intialization failed on AMD 5700X GPU (and possibly other recent AMD GPUs too), preventing the use of GPU acceleration.
Fixed: a fresh installation of PTGui could occasionally have the tooltips disabled. To fix this for everyone, this update will always enable tooltips even if they were disabled previously. Tooltips can be disabled (if desired) in the Options / Preferences.
Fixed: the option 'After sending projects to the Batch Stitcher: Close the Batch Stitcher when done' had no effect. It now works as expected. Still, this setting only has effect if the batch stitcher was not yet open. If the batch stitcher was already open (e.g. by using Tools - Batch Stitcher), it will remain open regardless of this setting.
Fixed: levelling a panorama would not work perfectly if the project contains viewpoint corrected images. PTGui now ignores viewpoint corrected images when levelling (provided there are at least 3 images without viewpoint correction).
Fixed: PTGui would crash when loading a .png image with indexed colors (palette) and transparency.
Fixed: A wrong compass angle (GPSImageDirection) would be embedded in panoramas stitched from Theta Z1 images.

New in PTGui Pro 11.14 (Jul 1, 2019)

PTGui now requires macOS 10.9 or later, or Windows 7 or later.
PTGui from now on uses LibRaw for decoding camera RAW files. DCRaw remains available as a fallback option. This brings support for RAW files from a few recent cameras (including Nikon Z7)
Improved default lens parameters for Ricoh Theta Z1 and Xiaomi Mijia Mi Sphere 360, resulting in less geometric disctortion. Even with this improvement, it's still necessary to create a template for your specific camera. See Q6.43.
Support for camera orientation sensor (for automatic levelling). Currently this is supported for Ricoh Theta Z1 DNG files, Xiaomi Mijia Mi Sphere 360 and images from DJI drones. Mi Sphere and Z1 images will be levelled automatically. A set of images from DJI drones will be pre-aligned when starting a new project. This can be disabled (in PTGui Pro only) in Project Settings - Miscellaneous.
Dual fisheye images (from one-shot 360 cameras): the first image is now placed in the center of the panorama. Previously the two images were placed at the left and right hand side of the equirectangular image. With the new placement it's easier to inspect the seams.
PTGui Pro: new option in Project Settings - Template Behavior: 'Preserve original orientation of the panorama'. If enabled, PTGui tries to preserve the orientation of the panorama as a whole, even if the template modifies the yaw/pitch/roll of individual images. It first applies the image positions from the template, but then the panorama is moved/rotated as a whole (without modifying the relative alignment between images) such that the images are positioned as before applying the template as much as possible. This is useful if the images have been positioned using orientation sensor data: the template will fine tune the relative alignment of the images, without affecting the overall levelling of the panorama.
Batch Builder (PTGui Pro): new option 'Delete project files after batch processing'. If enabled, the project file will be deleted as soon as the panorama has been stitched.
Batch Builder (PTGui Pro): new option 'Send the generated Batch List to the Batch Stitcher'. If checked, the question 'Would you like to send the generated Batch List to the Batch Stitcher now?' will be bypassed. This is useful if a large number of project files is generated (taking some time).
Added sensor size data of new cameras
Fixed: PTGui Viewer on macOS would show a cropped part of the viewer after resizing or maximizing the window.
Fixed: exposure data was not read from images from Insta One X
Fixed: 'assert failed' error when using SmartBlend, if one of the source images was completely outside the visible area of the panorama
Fixed: Batch Builder no longer asks 'PTGui found ... image(s) in the same folder, taken around the same time. Would you like to add these to your project as well?'.
Fixed: raw images could not be loaded if the file names contain non-western characters.

Changed the curve of the Pencil Size slider in the Mask tab. Smaller sizes now make up a larger portion of the slider.
Added Russian translation (thanks Andrey Ilyin!) and improved other translations (thanks Harald Bendschneider, Helmuth E. Günther, Thomas Bredenfeld, Erik Krause, Jeasung Park, Mario Carvajal, Lopertyur)
Keyboard shortcut Shift+Ctrl/Cmd+J for 'Generate control points for all overlapping images'
Batch Stitcher: new context menu item: Open Containing Folder; opens the project file location in Finder / Explorer
Added lens profile for Kandao Obsidian R
Fixed: Batch Stitcher: if Project Settings - Batch Stitcher Actions - 'only if enough control points found' is selected, and insufficient control points were found, the project would be marked as Done (with a green check mark). Now it will be marked in the Batch Stitcher as Failed (with a red cross).
Fixed: 'assertion failed' error when loading images from certain cameras
Fixed: layer names in Photoshop output were garbled if they contained non-ascii characters
Fixed: numbering for individual image layers in Photoshop output would start from 0 instead of 1
Fixed: individual layers would be output in a different order than in which they appeared in the project. They now follow the same order again
Fixed: when outputting individual layers, PTGui could skip images if they were outside the visible area of the panorama. Now a file (or Photoshop layer) will be created for every source image.
Fixed: crash when deleting all images except one from a set of linked bracketed images
Fixed: manually linking images (by right clicking in the Source Images tab) would change the order of the images.
Fixed: on Windows, PTGui would by default use the language selected in 'Regional Settings' in Control Panel. It will now use the language selected in Preferred Languages in Region and Language. This default language can be overridden in Options.
Fixed: Mac: Tools - Open Folder would not open the selected folder, but its parent folder

New in PTGui Pro 11.8 (Nov 10, 2018)

New in PTGui Pro 11.7 (Nov 2, 2018)

PTGui has been translated and can now run in multiple languages: English, Deutsch, Nederlands, Español, Français, Português, ???, ??? and ??. The language can be selected in Options/Preferences.
Added lens profile for GoPro Hero 5 Black
Support for dual fisheye images from Ricoh Theta V and Insta 360 One X
Added sensor sizes for several new cameras
Typing a custom size in the Create Panorama tab now switches the output size mode to 'fixed at ... megapixels', so the custom size will stick when running the optimizer
Delete Worst Control points works much better now. This also causes better rejection of control points on moving objects (e.g. clouds)
Performance improvements in panorama editor and detail viewer when using GPU acceleration
Improved resilience against crashing OpenCL drivers. If the OpenCL driver crashes it should now be possible to start PTGui with GPU acceleration disabled.
If the output folder for the panorama does not exist, it will be created automatically when stitching the panorama
Batch Stitcher: new function File | Append Batch List. This adds all projects from the selected Batch List to the currently active Batch List.
Batch Builder: if the batch stitcher is still busy stitching the previous Batch List when sending another Batch List to the Batch Stitcher, it will now offer to append the new batch list instead of replacing the active batch list.
Fixed: Lens database associations for GoPro cameras were ignored
Fixed: When tone mapping LDR panoramas containing some black areas, the tone mapped panorama could be completely black.
Fixed: Importing a PTGui 10 project containing individual lens parameters (circular fisheye) would result in the wrong lens parameters being assigned
Fixed: Under some circumstances, straight lines near the center of a wide angle fisheye image could become curved
Fixed: Fill Yaw (right click in Image Parameters table) didn't function correctly
Fixed: Batch Builder: if the 'one subfolder per camera' configuration was used, the images in the generated projects would be sorted by the file names. This could result in unexpected swapping of images. Images are now sorted by the name of the containing folder.
Fixed: File name suffixes for cube face filenames (as set in Tools - Convert to Cubic) were not preserved across restarts
Fixed: Windows: crash when loading corrupted jpeg files
Fixed: When editing and re-saving images in another application while they are loaded in PTGui, PTGui could pop up an error message about corrupt or empty files. PTGui will now wait until the image is saved completely by the other application.
Fixed: PTGui would use 'circular fisheye' for the tokina 10-17 at 10mm, while it could use fullframe fisheye
Fixed: For large panoramas PTGui would create too large temporary files (up to 2 TB each), wasting temporary disk space when stitching large panoramas.
Fixed: Windows: crash if the drive containing temporary files is disconnected while PTGui is running (e.g. in case of an external USB drive)
Fixed: Assertion Failed error when optimizing lens flare in the Exposure/HDR tab.
Fixed: PTGui failed to read certain LZW compressed TIFF files
Fixed: PTGui Viewer would display a garbled panorama if the image was not a 2:1 360x180 image
Fixed: Stitching a project on the command line using '-stitchnogui' would fail if a relative path name was given
Fixed: Stitching a Batch List on the command line using '-stitchnogui' would fail randomly

First of all: software piracy has been a ongoing problem for almost the entire 17 years of PTGui's existence. To protect against piracy PTGui 11 will require online activation upon installation. The licensing itself has not been changed, e.g. a personal license may still be installed on up to 3 computers simultaneously for personal use, it's just that we now enforce this limit through activation. We've made it as user friendly as possible: if you buy a new computer PTGui can be deactivated with one click and immediately moved to a different machine. For computers not connected to internet an offline activation method is provided. Activations can be managed online using just the license key. And in case of a hard disk crash, a stolen laptop, etc., you will be able to recover the license and install PTGui on a replacement computer.
New, dark-themed user interface. Dark / Light window theme can be selected in Options / Preferences.
Full Retina and per-monitor HiDPI support (for high resolution screens)
Bracketed sets of images are now handled as a single image
True 'what you see is what you get' rendering in the Panorama Editor and Detail Viewer, using OpenCL GPU acceleration
Panorama Settings tab, Numerical Transform, Exposure Fusion settings and Tone Mapping settings have been moved to the Panorama Editor
Improved EXIF parsing, in many cases PTGui can now detect the lens model used, and determine if it is a fisheye or rectilinear lens.
Rectilinear and fisheye lenses are characterized by focal length instead of field of view
Lens shift is now characterized as a percentage of the long/short side dimensions of the image, so the parameters are now independent of rotation and size.
New 'fisheye projection' parameter, to provide support for all known fisheye projections.
PTGui includes lens presets for many known fisheye lens models. By knowing the lens projection, the cropping circle is set more accurately and more control points will be found.
Landscape and portrait images can now be mixed in the same project.
New Lens Database. The same entry can be used for landscape and portrait images. Entries can be associated with EXIF data, so the lens database entry is applied automatically when loading images from the same camera/lens.
New Camera Database, to store custom camera sensor sizes. Entries can be associated with EXIF data.
Viewpoint optimization can be enabled, and images can be excluded / included by right clicking the thumbnails in the Project Assistant.
Online activation: To protect against piracy PTGui 11 will require online activation upon installation. The licensing itself has not been changed, e.g. a personal license may still be installed on up to 3 computers simultaneously for personal use, it's just that we now enforce this limit through activation. We've made it as user friendly as possible: if you buy a new computer PTGui can be deactivated with one click and immediately moved to a different machine. There's a backup offline activation method for computers not connected to internet. Activations can be managed online using just the license key. And in case of a hard disk crash, a stolen laptop, etc., you will be able to recover the license and install PTGui on a replacement computer.
Image numbers now start at 1 instead of 0
New project file format: Over the years the PTGui .pts project file format has extended upon the original script file format used by Panorama Tools. All the new (and future) changes no longer fit well in this format; therefore PTGui 11 switches to a new JSON based file format. This will make it much easier to incorporate new features in the future. Of course PTGui 11 can read project files from previous versions. Also an 'export to PTGui 10' function is included to enable interoperability with previous versions and third party software, although this will not cover the new functionalities and parameters.
The Panorama Tools optimizer can no longer be used with PTGui; many of the new features such as the new fisheye lens model are incompatible with Panorama Tools.
The PTGui optimizer now natively supports 'line type' control points.
Smooth zooming in the Control Points, Crop and Mask tabs. Mac users can use Pinch gestures to zoom
Mac: Touchpad two-finger rotate gesture can be used to rotate the images in the Mask, Crop and Control Points tabs
Images can be re-ordered by dragging them in the Source Image tab. Multiple images can be dragged at once.
Batch Lists files are now supported in the standard version. Previously this was a Pro feature.
GPU acceleration under Windows for AMD GPUs now runs in 64 bit mode, allowing use of more than 2GB of GPU memory
BigTIFF support! Gigapixel panoramas can be output as .tif and are no longer limited to the proprietary Photoshop .psb format. The BigTIFF dialect is used automatically when the generated .tif image turns out to be larger than 4GB. Keep in mind that not all TIFF capable applications support BifTIFF files.
Reduced memory use when handling large panoramas in the GUI. When opening a project in PTGui 10 all images would be loaded in memory (and subsequently swapped to disk). PTGui 11 only keeps reduced size thumbnails in memory, loading full size images when needed.
When opening a project or adding new images, PTGui first reads any embedded thumbnail from the images. This results in a nearly instant panorama preview.
The OpenEXR library has been updated to v2.2, improving compatibility with other applications.
PTGui is now a single process application: multiple projects can be open in a single running PTGui application. The Batch Stitcher runs in the same process. In particular on Mac this is the expected behavior: there's only one icon visible in the Dock. File - Open and File - New will open a new window. Double clicking a .pts file will open a new PTGui window instead of replacing the existing one.
Improved ability to handle symmetrical panoramas: PTGui 10 could get confused by images taken from the center of a symmetrical room. It would place control points not only on overlapping images, but also between similar looking features on opposite sides of the room. This caused a completely misaligned panorama and confused users. PTGui 11's Align Images function handles this more intelligently and generally gives a perfectly aligned panorama.
Added option to use simple alpha blending instead of the default Multiband blending algorithm. This is useful for combining non overlapping images such as cube faces where multiband blending causes defects. And when stitching 32 bit HDR source images alpha blending may give better results .
The PTGui stand alone panorama viewer now uses Lanczos pixel interpolation, resulting in a sharper image (previously it used bilinear interpolation).
New menu option: Images -> Select -> Blend Plane, to select all images at a certain EV level. This replaces the EV selection button in Create Panorama -> Advanced.
Panorama output size can be fixed to either a percentage of the optimum size, or to a certain number of megapixels. The output size is recalculated automatically after changing the projection or field of view.
The scroll bars of the two images in the Mask tab can be linked, just like in the Control Points tab.
Optimizer now offers 3 choices for viewpoint optimization: Reset / Keep / Optimize. Reset disables optimization and will reset the viewpoint parameters to 0. Previously this had to be done manually after disabling viewpoint optimization.
Control point generator now supports equirectangular images as well.
Control point generator works well with 32 bit HDR source images. In PTGui 10 it was often necessary to add control points manually.
New menu item: Images -> Remove Excluded Images (also in context menu in Source Images tab)
New menu item: Images -> Exclude/Include [only] Selected Images (also in context menu in Source Images tab)
Images excluded from the panorama are indicated by a red cross over the thumbnail
sliders (e.g. Preview Exposure) now 'snap' at the value 0, so they can be easily reset to zero.
Additional menu and keyboard shortcuts for zooming to 10%, 25% and 50% in the Mask, Crop and Control Points tabs
Mac: Keyboard shortcut for toggling full screen mode: Ctrl+Cmd+F
Redesigned memory management, to improve stability and performance
If multiple temporary folders are configured, PTGui will now attempt to use all folders in a balanced way. This improves performance (similar to RAID 0) when stitching panoramas using 2 or more SSD drives for temporary storage. Previously it would store temporary files on the drive with the most space available.
Any temporary files created by PTGui are guaranteed to be removed after closing PTGui. Previously temp files would not be removed if PTGui crashed or was forcefully closed.
Temporary data is now written to disk in a few large files instead of many small ones, improving performance.
Windows: if a progress window is being shown ('please wait...'), the menu bar is still accessible. A new PTGui window can be opened via File - New Launch New Instance even when PTGui is busy.
Some Fujifilm cameras (incorrectly) record a focal length of 50mm in the EXIF data when a manual lens is used. PTGui identifies and corrects this.
EXR output: the compression algorithm and bit depth (32 bit full float or 16 bit half float) are now configurable
If stitching is canceled, or aborted due to an error, all incomplete output files will be deleted. Previously PTGui would leave unfinished corrupt files, potentially causing other applications to crash if they attempted to load the corrupt file.
Panorama Editor & Detail Viewer: added keyboard shortcut keys [B] [U] and [S] to switch to the Blended, Unblended and Seams preview, and shortcut [N] to toggle displaying of image numbers
It's now possible to tell the control point generator to look for control points only in overlapping image pairs (Pro version only). This should give a significant speed improvement when aligning gigapixel panoramas and reduces the chances of faulty control points. The images should be roughly positioned beforehand, using Align to Grid, by applying a template or by loading a PapyWizard XML file. This behavior can be enabled using the 'Images are already roughly positioned' flag in Project Settings - 'Align images' behavior. This flag also appears in the Project Assistant when appropriate, after applying a template, after applying a PapyWizard file or after using Align to Grid. Also a new option 'Generate Control Points for overlapping images' has been added to the Control Points menu.
The control points table in the Control Points tab has been moved to the right hand side of the window. Control point numbers are shown in the same color as the corresponding markers in the images. The table can be collapsed when it is not needed.
The contents of the metadata dialog box has been moved to a new Metadata tab in the main window.
Batch Builder: new layout. The options for combining and removing projects are no longer shown as hyperlinks in the projects list, but have been moved to the right-click context menu.
Batch Builder: new configuration 'Multiple cameras, one subfolder per camera'. This is intended for creating time lapse panoramas using multi camera rigs. The memory card from each camera should be copied to a separate subfolder. Each subfolder should contain the same number of images, in the same ascending numerical order. The generated project files will take one image from each folder.
Dedicated support for dual fisheye images from the Samsung Gear 360, Xiaomi Mijia Sphere and YI 360 cameras. These cameras produce a single image containing two circular images side by side. When adding such an image to a PTGui project the image will automatically be loaded twice, with different cropping circles and masks, positioned at -90 and +90 degrees yaw. This behavior can be disabled in Project Settings - Miscellaneous if necessary. This even works in the Batch Builder. Due to manufacturing tolerances there will be small differences between individual cameras of the same type, resulting in different small offsets of the image circles. A template can be created for each individual camera by taking a photo (outside, with no objects close to the camera), adding control points and optimizing. Then do File - Save As Template. This template can be used via File - Apply Template, or in the Batch Builder.
OpenCL is now initialized in the background. No longer shows the 'Initializing OpenCL...' window upon startup.
True command line stitching without showing any windows. Launch PTGui with the -stitchnogui flag, followed by one or more project files and/or batch lists. The command does not return until stitching has finished, so this makes it easy to include PTGui as part of a larger batch process.
On macOS launch as follows:
"/Applications/PTGui Pro.app/Contents/MacOS/PTGui Pro" -stitchnogui project1.pts project2.pts batchlist.ptgbatch
On Windows:
START "" /B "C:Program FilesPTGuiPTGui.exe" -stitchnogui project1.pts project2.pts batchlist.ptgbatch
New option in Project Settings - Template Behavior controls the way images are linked in the target project when applying a template. Three options:
Link images in the same way as in the template
Automatically link images based on exposure (EXIF)
Don't modify the way images are linked
This makes it possible (for example) to apply a template of a non-HDR project to an HDR project with bracketed images.
New option: Project Settings - Miscellaneous - Set the panorama projection to 360 equirectangular when loading wide angle images. This immediately changes the panorama projection when loading a spherical 2:1 image or an image with a field of view of 160 degrees or more. Re-projecting an equirectangular image can now be done just by loading a 2:1 equirectangular image into PTGui and dragging in the Panorama Editor.
Images can be included/excluded by right-clicking on the thumbnail in the Project Assistant, and in the Panorama Editor in 'edit individual images' mode.
Batch Stitcher: the ordering of projects can be modified. Projects can be dragged up and down by clicking in the left hand header.
Align Images will now center the panorama on the first image if all images initially were at yaw = 0 (which is the default for a new project)
New option: 'Control Point Editor -> Reset CP type to add when switching to different images'. If selected (which is the default), the 'CP type to add' in the Control Points tab will be reset to the default value after switching images. The default value is 'Normal' if two different images are selected, or 'Vertical Line' if the same image is selected in both panels.
Batch Builder: the 'Batch Stitcher actions - Do Align Images' setting from the template is now also shown in the Batch Builder. This setting is a common source of confusion, so this should make it more clear what the batch stitcher will be doing.
PTGui 11 continuously recalculates the control point distances in the background (PTGui 10 only did this when running the optimizer).
When loading a project or adding images, PTGui initially attempts to load the thumbnails embedded in the image file (if available). This gives a nearly instant panorama preview, even for panoramas consisting of hundreds of images.
The computer is now prevented from going to sleep while stitching, aligning and optimizing projects.
Convert to cube faces: this now adds the focal length to the EXIF data of the generated images. When loaded back in PTGui, the lens parameters are set to 90 degrees field of view.
Added sensor size data for many new camera models
PTGui now offers a straightforward method for assembling cube faces into an equirectangular image. Just start a new project, add the 6 cube face images and go straight to Create Panorama. The file names should match the Cube Face Names set in the Convert to QTVR/Cubic window. PTGui will use these names to figure out which of the 6 images is which cube face.
Improved 'Delete Worst Control Points'. PTGui 10 was very conservative and would often not remove outlying control points.
'Feather' field in Create Panorama now has a numerical entry box as well

New in PTGui Pro 11 Beta 12 (Jun 18, 2018)

The .pts project file format has been changed in an incompatible way. This beta can read project files created with earlier betas, but earlier betas will not be able to read projects created in this beta.
Documentation is now included. Detailed help is now provided mostly in tooltips. Overview documentation for each window is available by pressing F1 (Windows), Fn+F1 (Mac) or by pressing the Help buttons.
dcraw updated to 9.28
Batch Stitcher: double clicking on a project in the batch stitcher queue will open the project in a new window
Added lens data for Insta 360 Pro
Faster loading of source images, in particular from spinning hard disks.
PTGui no longer permits optimization of the fisheye factor and a/b/c at the same time. These parameters interfere and should therefore be optimized separately.
Feather' field in Create Panorama now has a numerical entry box as well
Dark / Light window theme can be selected in Options / Preferences.
PTGUi windows can now be moved around the screen by dragging the toolbar (previously only the title bar could be dragged)
The command line options -x (to close the batch stitcher when done) and -d (to delete the project file after stitching has completed) have been added. They were available in PTGui 10 but still missing in PTGui 11.
If projects are added to a running batch stitcher using the -batch command line option, PTGui no longer steals keyboard focus. The batch stitcher will process the files without bringing the window to the front.
When opening Numerical Transform using the keyboard shortcut, the first field (Yaw) gets keyboard focus
Edit Individual Images mode in the panorama editor now behaves as in PTGui 10: while dragging an image, the image becomes semi transparent
Fixed: when launching PTGui, the panorama editor or other windows would be opened on top of the main window. Now the main window will be on top.
Fixed: several causes of crashing.
Fixed: Error message 'unsupported image format' for Samsung .srw files.
Fixed: Certain raw files would be loaded 90 degrees rotated.
Fixed: Mac: single line text fields (e.g. the Output File field in Create Panorama tab) would perform word wrapping internally, so not the entire contents of the field was shown.
Fixed: Sorting the control point table by image number did not always work
Fixed: A line could be visible in the result when remapping a spherical equirectangular image
Fixed: moving a control point by holding down the keyboard arrow keys would generate many Undo steps. Now the entire move can be reverted with one Undo step.
Fixed: On Windows 10, in certain cases after starting PTGui only a small strip of the PTGui windows would be visible
Fixed: Windows: if windows were maximized on different monitors, PTGui did not properly restore the window positions; windows would be opened maximized on a different monitor.
Fixed: Assertion Failed error when deleting control points from the Control Points table.

Further improvements to the control point generator
When editing control points in bracketed images, the previous PTGui 11 betas would pop up a window asking in which of the bracketed images the control points should be added. This is no longer necessary, PTGui will decide in which images the control points should be placed and the Control Points tab will keep showing the merged bracketed images.
If 'auto add' is enabled, the control point will be added to the most appropriate EV (i.e. the one which is not over- or underexposed at the given control point location).
If Auto Add is not enabled, the new control point will use the middle (0EV) exposures.
The 'generate control points here' function will analyze and add control points to all pairs of EVs separately.
It's still possible to add control points to a specific pair of images from the bracketed set by using the popup balloons from the list of thumbnails in the Control Points tab, or by using the Ctrl+Alt+Up/Down (Windows) or Cmd+Alt+Up/Down (Mac) keyboard shortcuts.
When loading a project or adding images, PTGui initially attempts to load the thumbnails embedded in the image file (if available). This gives a nearly instant panorama preview, even for panoramas consisting of hundreds of images.
The computer is now prevented from going to sleep while stitching, aligning and optimizing projects.
Now properly handles the situation if images have different dimensions or bit depth than at the time the project was saved. When loading such a project, it is updated with the new image sizes; masks and control points are scaled to the new dimensions.
Images are reloaded automatically if they are edited in another application.
Performance improvement for the user interface when handling very large panoramas (1000s of images). The user interface would keep locking up for a second while changing the projection parameters in the Panorama Editor.
Convert to cube faces: this now adds the focal length to the EXIF data of the generated images. When loaded back in PTGui, the lens parameters are set to 90 degrees field of view.
Added lens profile for Samsung Gear 360 (2017 model)
Added sensor size data for many new camera models
Fixed: reduced memory usage and increased speed for rendering very large panoramas containing masks
Fixed: the 'Bracketed Exposures' window (which pops up when pressing Align Images) did not show the Exposure Fusion / True HDR choice. It now does, like PTGui 10.
Fixed: the PTGui Viewer could fail with the error 'No compatible GLSL version found'
Fixed: Windows: when zooming in the Control Points / Mask tab, the left hand image would refresh immediately but the right hand image would be updated only after some time.
Fixed: PTGui would output non standard data in the exif ISOSpeedRatings field. Other applications would not read the ISO value from files generated by PTGui.
Fixed: When outputting a panorama in rectilinear or fisheye projection, the focal length value embedded in the EXIF data was wrong
Fixed: random crashes

New in PTGui Pro 11 Beta 7 (Mar 14, 2018)

Align Images will now center the panorama on the first image if all images initially were at yaw = 0 (which is the default for a new project)
New option: 'Control Point Editor -> Reset CP type to add when switching to different images'. If selected (which is the default), the 'CP type to add' in the Control Points tab will be reset to the default value after switching images. The default value is 'Normal' if two different images are selected, or 'Vertical Line' if the same image is selected in both panels.
Batch Builder: the 'Batch Stitcher actions - Do Align Images' setting from the template is now also shown in the Batch Builder. This setting is a common source of confusion, so this should make it more clear what the batch stitcher will be doing.
PTGui 11 continuously recalculates the control point distances in the background (PTGui 10 only did this when running the optimizer). This is now done at a slightly lower priority, so that it does not affect user interface responsiveness.
Options/preferences: checkbox 'Show rounded values when the cursor is not in a numeric field' is back, this was missing from the previous PTGui 11 betas.
Detail viewer: reversed the direction of the zoom slider, it is now the same as PTGui 10: Upwards zooms in, downwards zooms out
Fixed: 'Resolution' field in metadata could not be changed from the default 300 ppi.
Fixed: Control Points Table window: the scrollbar would not be shown if the window was too small
Fixed: Horizontal control points were ignored (only vertical line control points were used) by the Level Panorama function
Fixed: Project Settings: the checkbox 'Initialize the lens settings for each project using EXIF data in the images (override lens settings in this template)' is cleared after loading the first image. So the batch builder will (by default) only look at the EXIF data if the template is an empty project. This is the original behavior, but beta 4-6 failed to do this.
Fixed: Batch Builder: if the 'Initialize the lens settings for each project using EXIF data in the images (override lens settings in this template)' was set, the entire Project Settings page in the template was ignored. In combination with the preceding bug, this happened for every project.
Fixed: Convert to Cubic/QTVR: a too small cube face size would be used if set to Automatic
Fixed: When restarting, PTGui did not remember if the panorama editor, detail viewer and control points table were visible
Fixed: if the panorama editor window was minimized to the task bar, pressing the Ctrl+E shortcut didn't restore the window. The same applied to all other tool windows.
Fixed: failed to load certain LZW compressed TIFF images (resulting in white/blue checker pattern)
Fixed: On Windows 7, with the Classic Theme enabled, the title bars and borders of the windows were missing
Fixed: With certain Windows display settings, the image numbers in the Panorama Editor and Detail Viewer were missing
Fixed: Windows 10: when using multiple monitors, if a window was maximized it would draw a grey border at the edge of the other monitor
Fixed: Mac: PTGui viewer would crash on older machines (without AVX support).
Fixed: 'always on top' buttons in the Panorama Editor and Detail Viewer did not work
Fixed: Auto Add would place control points at wrong location if one of the images contained overexposed (pure white) areas
Fixed: Auto Add (in the Control Points tab) now gives keyboard focus to the target image. So the keyboard arrows will move the target point instead of the source point
Fixed: Using the keyboard keys in the control points tab now move the mouse pointer and the zoomer, to follow the control point
Fixed: Apply Template ignored any individual Crop offset settings
Fixed: mac: PTGui could be hidden behind other windows after launching. It is now started in the foreground.
Fixed: random crashes

New in PTGui Pro 11 Beta 6 (Feb 19, 2018)

New in PTGui Pro 11 Beta 5 (Feb 14, 2018)

New in PTGui Pro 11 Beta 4 (Feb 14, 2018)

Beta 4 contains many new features and improvements:
It's now possible to tell the control point generator to look for control points only in overlapping image pairs (Pro version only). This should give a significant speed improvement when aligning gigapixel panoramas and reduces the chances of faulty control points. The images should be roughly positioned beforehand, using Align to Grid, by applying a template or by loading a PapyWizard XML file. This behavior can be enabled using the 'Images are already roughly positioned' flag in Project Settings - 'Align images' behavior. This flag also appears in the Project Assistant when appropriate, after applying a template, after applying a PapyWizard file or after using Align to Grid. Also a new option 'Generate Control Points for overlapping images' has been added to the Control Points menu.
The control points table in the Control Points tab has been moved to the right hand side of the window. Control point numbers are shown in the same color as the corresponding markers in the images. The table can be collapsed when it is not needed.
The Fill Yaw function is available again: select a group of images in the Image Parameters tab, then right click and select 'Fill Yaw' from the context menu.
The contents of the metadata dialog box has been moved to a new Metadata tab in the main window.
Batch Builder: new layout. The options for combining and removing projects are no longer shown as hyperlinks in the projects list, but have been moved to the right-click context menu.
Batch Builder: new configuration 'Multiple cameras, one subfolder per camera'. This is intended for creating time lapse panoramas using multi camera rigs. The memory card from each camera can be copied to a separate subfolder. Each subfolder should contain the same number of images, in the same ascending numerical order. The generated project files will take one image from each folder.
Individual Crop is back. It's slightly different from PTGui 10: in PTGui 11 individual crop only applies to the position (not the size) of the cropping circle/rectangle. The size of the cropping area is part of the lens parameters, so it is common to all images sharing the same lens.
Dedicated support for dual fisheye images from the Samsung Gear 360, Xiaomi Mijia Sphere and YI 360 cameras. These cameras produce a single image containing two circular images side by side. When adding such an image to a PTGui project the image will automatically be loaded twice, with different cropping circles and masks, positioned at -90 and +90 degrees yaw. This behavior can be disabled in Project Settings - Miscellaneous if necessary. This even works in the Batch Builder. Due to manufacturing tolerances there will be small differences between individual cameras of the same type, resulting in different small offsets of the image circles. A template can be created for each individual camera by taking a photo (outside, with no objects close to the camera), adding control points and optimizing. Then do File - Save As Template. This template can be used via File - Apply Template, or in the Batch Builder.
Added lens parameters for Meike MK-6.5mm f2.0 Fisheye, GoPro Fusion, Xiaomi Mijia Mi Sphere 360 and YI 360.
OpenCL is now initialized in the background. No longer shows the 'Initializing OpenCL...' window upon startup.
True command line stitching without showing any windows. Launch PTGui with the -stitchnogui flag, followed by one or more project files and/or batch lists. The command does not return until stitching has finished, so this makes it easy to include PTGui as part of a larger batch process.
On macOS launch as follows:
"/Applications/PTGui Pro.app/Contents/MacOS/PTGui Pro" -stitchnogui project1.pts project2.pts batchlist.ptgbatch
On Windows:
START "" /B "C:Program FilesPTGuiPTGui.exe" -stitchnogui project1.pts project2.pts batchlist.ptgbatch
New option in Project Settings - Template Behavior controls the way images are linked in the target project when applying a template. Three options:
Link images in the same way as in the template
Automatically link images based on exposure (EXIF)
Don't modify the way images are linked
This makes it possible (for example) to apply a template of a non-HDR project to an HDR project with bracketed images.
New option: Project Settings - Miscellaneous - Set the panorama projection to 360 equirectangular when loading wide angle images. This immediately changes the panorama projection when loading a spherical 2:1 image or an image with a field of view of 160 degrees or more. Re-projecting an equirectangular image can now be done just by loading a 2:1 equirectangular image into PTGui and dragging in the Panorama Editor.
Load Mask and Paste Mask now merge the pasted/loaded mask with the existing mask (instead of replacing). This is the same behavior as in PTGui 10. To truly replace a mask, clear it first.
Improved mouse response in Mask tab
Images can be linked/unlinked using the right-click context menu in the Source Images tab.
It's now possible to make disjoint selections by holding down the Control key (Windows) or Command key (Mac) while clicking cells. This works in e.g. the Source Images tab, Image Parameters tab and in the Control Points table.
Images can be included/excluded by right-clicking on the thumbnail in the Project Assistant, and in the Panorama Editor in 'edit individual images' mode.
Batch Stitcher: the ordering of projects can be modified. Projects can be dragged up and down by clicking in the left hand header.
Performance improvements and reduced memory usage.
Many cosmetic improvements in user interface.
All windows and dialog boxes have now been converted to the new dark themed layout.
All windows now have a dark themed title bar in Windows 10.
Fixed: Batch Builder would ignore any individual lens parameters (or multiple global lenses) in the project
Fixed: Mac: Enter key to confirm did not work in some dialog boxes and in the Image Parameters tab
Fixed: Windows: the keys RGEDFKL triggered the Mask menu shortcuts even when the cursor was in a text field, so it was not possible to enter those characters as part of the output file name.
Fixed: dragging the cropping area, or dragging the selection rectangle in the Control Points tab would move in the wrong direction if the image was rotated 90 degrees.
Fixed: moving or resizing the cropping area would generate many small Undo steps, instead of a single Undo step for the entire movement.
Fixed: Replace Images failed when attempting to replace multiple images with identically named files in a different folder
Fixed: Olympus ORF files were loaded 90 degrees rotated
Fixed: 'Load Mask' was missing from the Source Images context menu, so it was not possible to load a mask for multiple images at once.
Fixed: Align to Grid: the grid was always applied starting at the first image. The image range set in the 'apply to' section was ignored.
Fixed: using the cursor keys in certain grids (CP table, source images table) did not scroll the selection into view.
Fixed: Panorama Editor grid lines were hardly visible on high DPI / retina screens.
Fixed: Export to PTGui 10 would create corrupted project files if the source image file names contained non-western characters.
Fixed: Optimization did not keep images without control points in place. This caused problems when running Align to Grid if some images contained only blue sky.
Fixed: When using HDR source images the thumbnails would be displayed with a wrong gamma curve (exaggerated contrast).
Fixed: Mac: closing a full screen window would leave an empty black window on the screen.
Fixed: GPU accelerated stitching failed with 'Unknown Error' on certain nvidia cards (Quadro, GT630 and others).
Fixed: 'Generate Control Points Here' often failed when using 32 bit HDR source images.
Fixed: 'Link Scrollbars' (CP and Mask tab) did nothing if the same image was selected in both panels.
Fixed: If a Preview Exposure was set, the mouse pointer in the Mask and Control points tab could become invisible (black on black).
Fixed: 'Auto Add' in the Control Points tab did not function if the images were displayed rotated.
Fixed: Image numbers did not appear in the Panorama Editor when running under Windows 7

New in PTGui Pro 11 Beta 3 (Sep 18, 2017)

Redesigned memory management, to improve stability and performance
If multiple temporary folders are configured, PTGui will now attempt to use all folders in a balanced way. This improves performance (similar to RAID 0) when stitching panoramas using 2 or more SSD drives for temporary storage. Previously it would store temporary files on the drive with the most space available.
Any temporary files created by PTGui are guaranteed to be removed after closing PTGui. Previously temp files would not be removed if PTGui crashed or was forcefully closed.
Temporary data is now written to disk in a few large files instead of many small ones, improving performance.
Windows: if a progress window is being shown ('please wait...'), the menu bar is still accessible. A new PTGui window can be opened via File - New Launch New Instance even when PTGui is busy.
Better error message when attempting to level a panorama consisting of a single source image (levelling requires 2 or more source images).
Some Fujifilm cameras (incorrectly) record a focal length of 50mm in the EXIF data when a manual lens is used. PTGui identifies and corrects this.
If the Camera Sensor Size and Focal Length dialogs (which pop up when EXIF data is not available when adding a new image to a project) are canceled, the image is still added to the project. This is the same behavior as in PTGui 10.
Added lens data for Nikon AF-S Fisheye - Nikkor 8-15mm f/3.5 - 4.5E ED
Windows: the installer now supports silent installation: PTGuiSetup.exe /S /D=C:Program FilesPTGui
Faster scrolling when clicking in a scrollbar outside the thumb
EXR output: the compression algorithm and bit depth (32 bit full float or 16 bit half float) are now configurable
If stitching is canceled, or aborted due to an error, all incomplete output files will be deleted. Previously PTGui would leave unfinished corrupt files, potentially causing other applications to crash if they attempted to load the corrupt file.
Panorama Editor & Detail Viewer: added keyboard shortcut keys [B] [U] and [S] to switch to the Blended, Unblended and Seams preview, and shortcut [N] to toggle displaying of image numbers
After placing the first marker of a control point, the marker can be moved using the cursor keys
When placing the second marker of a control point, the magnifier for the first point will remain visible
Changed the wording of the 'use EXIF' checkboxes in Project Settings
Fixed: PTGui could crash randomly
Fixed: Apply Template would delete all control points
Fixed: Apply Template did not copy all settings from the template (a.o. Exposure and color adjustment settings)
Fixed: a vertical line could be visible when remapping a 360 degree source image or when creating a Philosphere
Fixed: error for certain tiff files: "Invalid TIFF file: number of elements in BitsPerSample should equal SamplesPerPixel"
Fixed: Batch Builder would display certain thumbnails rotated by 90 degrees
Fixed: Assertion Failed error when stitching large equirectangular panoramas
Fixed: when optimizing a panorama with only vertical/horizontal line control points, and 'Level in second pass' selected, running the optimizer would show the error 'failed to achieve a good alignment of the images' even though levelling succeeded.
Fixed: for manual lenses on certain cameras an aperture of 'nan' (not-a-number) was detected from EXIF
Fixed: reloading the active project (e.g. via File - Recent Projects) would clear the panorama editor
Fixed: Auto Jump did not work if two identical images were selected in the CP tab (for adding hor/vert line control points)
Fixed: Windows: some dialogs could not be dismissed (Cancel) using the Escape key
Fixed: If default project settings were changed using 'Make Default', PTGui would ask to save changes even if the project was a new project without any modifications.
Fixed: If Make Default was done with a project in Simple mode, subsequent File-New would open in Advanced mode
Fixed: Straightening a panorama failed for multi row panoramas with a narrow vertical field of view
Fixed: color profiles in TIFF files were ignored. The resulting panorama would not have the color profile embedded, causing color differences.
Fixed: some of the keyboard shortcust were labeled "Ctrl+Alt", others "Alt+Ctrl"
Fixed: Images -> Select -> Blend Plane is enabled for HDR projects only
Fixed: When applying a PTGui 10 template, the panorama output dimensions could be changed to a very large value
Fixed: crash if writing a jpeg or tiff file failed (e.g. due to full disk). Now shows an error message instead.
Fixed: progress bar on mac looked ugly at small percentages
Fixed: exporting a project with 'link pitch' or 'link roll' to PTGui 10 would save a project with all pitch/roll optimization checkboxes cleared
Fixed: Mac: keyboard shortcuts for the Mask menu were not shown
Fixed: Control Points tab: Ctrl+Alt+arrow keys didn't work properly if the HDR blend plane selection popup balloon was shown
Fixed: right-click in the panorama editor: the context menu would show other images than the ones below the mouse pointer
Fixed: Mac: Ctrl+left mouse button didn't work as an alternative for the right mouse button (for context menu, dragging)
Fixed: Mac: dragging/dropping files from Finder into PTGui would keep the Finder locked up while PTGui was showing a dialog box
Fixed: Control points for images having the 'use control points of' flag cleared now have an empty distance value in the control points table
Fixed: The numbers in the control point markers did not match the numbers in the control points table
Fixed: External blenders (smartblend, enblend) would be run without the 'wrap 360 degree' flag even though the panorama had 360 degrees field of view

New in PTGui Pro 10.0.17 (Sep 7, 2017)

New in PTGui Pro 11 Beta 2 (Jul 14, 2017)

PTGui 11 no longer inherits the PTGui 10 'File - Make Default' settings but uses its own presets.
If the panorama size is set to e.g. 50% of optimum size, this now means half the width and half the height (i.e. 25% of the number of pixels). The first beta would set it to 50% of the area, i.e. 71% of width and height.
Enabling Viewpoint Correction in the Project Assistant no longer switches the project to Advanced mode
Zoomer is not shown while shift+dragging a selection box in the Control Points tab
Scroll bars are wider under Windows
New menu item: Images -> Remove Excluded Images (also in context menu in Source Images tab)
New menu item: Images -> Exclude/Include [only] Selected Images (also in context menu in Source Images tab)
Images excluded from the panorama are indicated by a red cross over the thumbnail
Calibrated lens parameters added for these lenses: Samsung 10mm f3.5 Fisheye, Nikon AF Fisheye Nikkor 16mm f2.8D, Sigma 10mm F2.8 EX DC HSM Fisheye, Panasonic Lumix G 8mm f3.5 Fisheye, Sigma 8mm F4 EX Circular Fisheye, Entaniya 220, Entaniya 250 and Entaniya 280.
sliders (e.g. Preview Exposure) now 'snap' at the value 0, so they can be easily reset to zero.
For rectilinear and fisheye lenses the horizontal field of view can now be specified in the Lens Setttings tab.
Additional menu and keyboard shortcuts for zooming to 10%, 25% and 50% in the Mask, Crop and Control Points tabs
Mac: Keyboard shortcut for toggling full screen mode: Ctrl+Cmd+F
Mac: Touchpad two-finger rotate gesture can be used to rotate the images in the Mask, Crop and Control Points tabs
Fixed: several bugs causing PTGui to crash
Fixed: several bugs causing 'Assertion failed' errors
Fixed: Align Images could result in an upside down panorama
Fixed: wrong stereographic projection if compression was not set to maximum
Fixed: garbled output for Vedutismo projection
Fixed: blending with Smartblend or Enblend caused a crash
Fixed: failed to load LZW compressed TIFF files (Blue/white checkered pattern)
Fixed: wrong mouse pointer when hovering ovre the scroll bars in Control Points and Mask tab
Fixed: Align Images could fail to find control points if some of the images are identical or overlap exactly
Fixed: if two images overlap exactly and 'show seams' is enabled, a random pattern of red dots would be visible.
Fixed: in certain circumstances parts of a source image would not be used, leaving a hole in the blended panorama
Fixed: in certain circumstances PTGui generated broken photoshop files
Fixed: moving a control point using the keyboard arrows would move in the wrong direction if the image was displayed rotated
Fixed: Preview size was not imported correctly from PTGui 10 projects
Fixed: error '' is not a number when importing a PTGui 8 project
Fixed: optimizer tab: if individual lens/shift parameters were used, some of the columns in the table were too wide
Fixed: crash when closing the window and choosing 'Yes' when asked to save the modified project
Fixed: Several bugs related to File - Make Default
Fixed: Mouse cursor could be invisible (e.g. black on black) in Control Points and Mask tab
Fixed: 'Generate Control Points for images .. and ..' was not available or displayed the wrong image numbers
Fixed: holding down Ctrl (Cmd on mac) while dragging a control point marker slows down the mouse additionally (as in PTGui 10).
Fixed: PTGui could hang during control point generating (or during Align Images)
Fixed: PTGui Viewer would crash if an unsupported file format was dropped onto the window
Fixed: PTGui Viewer would crash if a new file was dropped onto the window while it was still busy loading the previous panorama
Fixed: In Mask tab, if zoom level was zet to 'Fit', selecting 'Zoom In' would actually zoom out
Fixed: Optimizer could optimize the lens parameters towards extreme wide or narrow focal length and get stuck
Fixed: Thumbnails of source images could be blurry

New in PTGui Pro 11 Beta 1 (Jun 10, 2017)

The most obvious change is a new modern, dark themed user interface. PTGui 11 uses collapsible panels to make the tools available where you need them but without occupying precious screen real estate. The familiar row of tabs at the top of the window have been moved to a vertical panel at the left side, to be more consistent with current user interface concepts. The side bar can be collapsed to make more space available. The numbered tabs for selecting images (e.g. in the Control Points tab) have been replaced with image thumbnails, so you can see which image is which. And PTGui 11 is fully compatible with Retina screens and supports per-monitor high DPI under Windows.
In the Pro version handling of HDR panoramas has been much improved. Throughout the entire user interface bracketed sets of images are now treated as a single image. Each bracketed set is represented by a single exposure fused thumbnail image. So for example, when using 3 step bracketing you now only have to deal with 5 images instead of 15! The control points editor simultaneously shows all control points for the combined images in two bracketed sets. It is also possible to view individual images (a.o. using the keyboard shortcut Ctrl+Alt+Up/Down on Windows, or Cmd+Alt+Up/Down on Mac). The Image Parameters screen can be collapsed to show bracketed groups or it can be expanded to edit the parameters of individual images in each set.
The Panorama Editor and Detail Viewer now use the same stitching engine as used for the final render. This gives a true WYSIWYG preview of the panorama, in real time, properly blended and anti aliased at screen resolution. No more blurry previews in the Panorama Editor or shimmering in the Detail Viewer! The panorama editor in PTGui Pro 10 had limited functionality when working with HDR panoramas. Not so any more: you now get a live tone mapped or exposure fused preview. HDR settings can be adjusted right in the panorama editor, in the collapsible side bar panel. The Panorama Editor and Detail Viewer now benefit from OpenCL GPU acceleration.
EXIF metadata parsing has been improved as well. PTGui can now read most manufacturer dependent 'maker notes'; this allows it to not only determine the focal length but in many cases also the actual lens brand and model. The lens parameters will be initialized correctly, whereas PTGui 10 would sometimes mistake a wide angle rectilinear lens for a fisheye or vice versa.
Speaking of lenses, PTGui changes the parametrization of lens data: instead of characterizing a (rectilinear or fisheye) lens by its horizontal field of view, PTGui 11 stores the focal length. Lens shift (i.e. the offset of a lens' optical axis) is now stored as relative offsets on the short and long image dimensions, instead of absolute x/y pixel offsets. These two changes finally make it possible to mix portrait and landscape images in the same project. There's one caveat: for portrait images PTGui needs to know whether the camera was rotated clockwise or counter clockwise in order to apply the lens shift in the proper direction. This can be selected in the Lens Settings tab.
For fisheye lenses PTGui 11 introduces a new fisheye projection parameter (k in the formula below), allowing it to perfectly model all practical fisheye projections (equidistant, stereographic, orthographic and equisolid).
For some background see Fisheye Projection. Presets for many known fisheye lenses are included, and selected automatically when a known fisheye lens is recognized in the EXIF data. By knowing the exact fisheye projection PTGui is able to find more control points, particularly in the edges of fisheye images. Furthermore it allows PTGui to set the cropping circle (for circular fisheye lenses) more accurately.
The lens database has been redesigned and now includes the circular fisheye cropping parameters as well. Due to the new lens parametrization the same entry can be used for both portrait and landscape images. Lens database entries can be linked to EXIF data, resulting in the lens data to be set automatically when loading an image. Similarly there's now a camera sensor size database for automatically setting the sensor size / crop factor based on the EXIF data.
PTGui now supports multiple cameras and lenses in the same project. For example a gigapixel panorama might be taken with a long 300mm lens but such level of detail is not necessary for the sky. The sky images can now be photographed with a wider angle lens and stitched in the same project. The control point generator will find control points between images from different lenses. Exposure and vignetting optimization will use separate curves for each lens. In PTGui 11 it is possible to use vignetting correction when merging camera images with an already stitched equirectangular panorama.
Viewpoint optimization for an image can be enabled right from the Project Assistant, by right-clicking on the thumbnail. If viewpoint correction is enabled for an image, the control point generator will notice and it will find control points even if the image was taken from a significant viewpoint offset.
Over the years the PTGui .pts project file format has extended upon the original script file format used by Panorama Tools. All the new (and future) changes no longer fit well in this format; therefore PTGui 11 switches to a new JSON based file format. This will make it much easier to incorporate new features in the future. Of course PTGui 11 can read project files from previous versions. Also an 'export to PTGui 10' function is included to enable interoperability with previous versions and third party software, although this will not cover the new functionalities and parameters. Due to all incompatible changes the Panorama Tools optimizer can no longer be used with PTGui. However, the PTGui optimizer now natively supports 'line type' control points and thus covers all functionalities available in the Panotools optimizer.
Other changes:
Image numbers now start at 1 instead of 0
Smooth zooming in the Control Points, Crop and Mask tabs. Mac users can use Pinch gestures to zoom
Images can be re-ordered by dragging them in the Source Image tab. Multiple images can be dragged at once
Batch Lists files are now supported in the standard version. Previously this was a Pro feature
GPU acceleration under Windows for AMD GPUs now runs in 64 bit mode, allowing use of more than 2GB of GPU memory
BigTIFF support! Gigapixel panoramas can be output as .tif and are no longer limited to the proprietary Photoshop .psb format. The BigTIFF dialect is used automatically when the generated .tif image turns out to be larger than 4GB
Reduced memory use when handling large panoramas in the GUI. When opening a project in PTGui 10 all images would be loaded in memory (and subsequently swapped to disk). PTGui 11 only keeps reduced size thumbnails in memory, loading full size images when needed
The OpenEXR library has been updated to v2.2, improving compatibility with other applications
PTGui is now a single process application: multiple projects can be open in a single running PTGui application. The Batch Stitcher runs in the same process. In particular on Mac this is the expected behavior: there's only one icon visible in the Dock. File - Open and File - New will open a new window. Double clicking a .pts file will open a new PTGui window instead of replacing the existing one
Improved ability to handle symmetrical panoramas: PTGui 10 could get confused by images taken from the center of a symmetrical room. It would place control points not only on overlapping images, but also between similar looking features on opposite sides of the room. This caused a completely misaligned panorama and confused users. PTGui 11's Align Images function handles this more intelligently and generally gives a perfectly aligned panorama
Added option to use simple alpha blending instead of the default Multiband blending algorithm. This is useful for combining non overlapping images such as cube faces where multiband blending causes defects. And when stitching 32 bit HDR source images alpha blending may give better results
The PTGui stand alone panorama viewer now uses Lanczos pixel interpolation, resulting in a sharper image (previously it used bilinear interpolation)
New menu option: Images -> Select -> Blend Plane, to select all images at a certain EV level. This replaces the EV selection button in Create Panorama -> Advanced
Panorama output size can be fixed to either a percentage of the optimum size, or to a certain number of megapixels. The output size is recalculated automatically after changing the projection or field of view
The scroll bars of the two images in the Mask tab can be linked, just like in the Control Points tab
Optimizer now offers 3 choices for viewpoint optimization: Reset / Keep / Optimize. Reset disables optimization and will reset the viewpoint parameters to 0. Previously this had to be done manually after disabling viewpoint optimization
Control point generator now supports equirectangular images as well
Control point generator works well 32 bit HDR source images. In PTGui 10 it was often necessary to add control points manually

PTGui now comes with a standalone viewer (Windows and Mac) for equirectangular panoramas. The viewer can also be used outside of PTGui. It supports full screen display on Windows and mac. On mac the trackpad can be used for navigation (swipe and pinch). The viewer can be launched through Tools - PTGui Viewer and via the View / Preview functions in PTGui.
New tone mapping algorithm for HDR panoramas with very natural looking results (Pro version)
The tone mapper (PTGui Pro only) can now be used for LDR panoramas as well. This works great for boosting the shadows in a non-bracketed panorama and can (at low ISO) avoid the need to shoot bracketed images.
New menu Images - Select: this allows for example to delete all images outside the visible area of the panorama. Or in conjunction with the yellow crop lines in the panorama editor, to delete images any rectangular area of the panorama.
Options/Preferences - Advanced: RAM usage is now specified as an absolute number of megabytes; previously this was set as a percentage of available RAM
Faster loading of uncompressed tiff images from spinning hard disks (reduced chance of disk thrashing)
HDR/Exposure tab: section 'HDR' has been reworded
Windows: The installer now adds PTGui to the 'Send To' context menu in Explorer. In Explorer you can select a set of images to be stitched, right click and choose 'Send to -> PTGui'.
Set optimum size' button now directly picks the optimum size (formerly 'maximum size' in the popup menu). The options 'For print' and 'For web' have been removed.
Changes in the way external viewers are configured: In Options/Preferences - Advanced now up to 3 applications can be configured. These applications will be shown in the popup list under the View button (Create Panorama tab) and Preview button (Preview tab). The new PTGui Viewer is always included for equirectangular panoramas.
PTGui now checks upon startup whether the configured temporary folders exist and can be written to; it will warn if there is a problem.
Slightly improved detail in exposure fused result in areas with saturated colors
Updated dcraw to version 9.22
Added EXIF sensor size data for a number of cameras
Fix: mac: several windows had a keyboard shortcut Cmd+C for the Close or Cancel button. This would override the keyboard shortcut for copying to clipboard. These windows can now be closed using the Esc key and copying can be done using Cmd+C.
Fix: mac: if individual lens settings were used, PTGui would crash if the lens type for an image was changed in the Image Parameters tab
Fix: Minor layout issues in main window
Fix: Blending artifacts when stitching RAW images
Fix: Blending artifacts when generating HDR panoramas
Fix: PTGui web viewer will no longer use CSS3D in Firefox under Linux, due to rendering bugs in this browser
Fix: PTGui web viewer previously had a minimum size of approximately 300 pixels, causing problems on small (smartphone) screens
Removed support for 16 bit linear HDR output: previously PTGui Pro could save HDR output in a 16 bit fixed point TIFF or PSD file. This is no longer possible, HDR output is now 32 bit floating point or 16 bit half float EXR. Note that this was a rarely used feature, and regular 16 bit output is still fully supported for low dynamic range and tone mapped output.
PTStitcher is no longer supported
The 'Use Quicktime Player' option for previewing has been removed (current QuickTime versions do not support panoramas anymore)

New in PTGui Pro 9.2.0 (May 7, 2014)

Fix: crash if a corrupt jpeg file was loaded
Fix: memory leak when loading a file with corrupt EXIF data
Fix: possible crash when a source image is modified externally
Fix: sorting images (Sort button in the Source Images tab) could take a very long time
Fix: after optimization some control points could have a reported optimization distance of 0, while the actual error is very large
Fix: some settings saved by File - Make Default would be ignored if checkboxes in Project Settings - Template behaviour were unchecked
Fix: Numerical Transform window would show rounded values even if this was disabled in Options/Preferences
Fix: edges of the panorama were cut off for 360 degree circular fisheye output
Fix: Metadata window: certain GPS coordinates would be shown as e.g. 9.35999999... instead of 9.36
Fix: Mac: scrolling using the trackpad in the Batch Builder and Batch Stitcher windows didn't work correctly
dcraw updated to version 9.21
Wider input fields in Numerical Transform
Source images with file names containing numbers are now sorted intelligently: 'Image 20.jpg' now comes before 'Image 113.jpg'. Previously alphabetic ordering was used so '20' would come after '113'.
Added EXIF sensor size data for a number of cameras
PTGui Web Viewer:
Fix: In some browsers autorotating would stop after a while
Fix: In some browsers, if pan or tilt limits were set (partial panorama) the display would be corrupted or the viewer would stop responding
Fix: mouse wheel zooming did not work in Firefox
Fix: mouse wheel zooming would also scroll the web page in which the viewer was embedded
If minimum and maximum pan bounds are set, autorotation no longer stops at the edge but reverses direction
Right mouse click popup window: the text in this window has been changed from 'Created with PTGui' to 'PTGui Viewer version x.x'
On a mac the panorama can now be navigated by swiping with two fingers on the touchpad, or by swiping with one finger on the surface of the magic mouse. This can be disabled by adding 'enablemactouchpad: false' to the viewer options in the html source.
Dragging while holding down the right mouse button now also zooms in and out
When autorotation starts the viewer will navigate towards the horizon. This is still the default but this behaviour can be disabled by adding 'autorotatetohorizon: false' to the viewer options in the html source.

New in PTGui Pro 9.1.4 (Oct 26, 2012)

dcraw updated to version 9.16
PTGui Pro now supports layered Photoshop output for 32 bit HDR projects. Useful for manual retouching or deghosting
Batch Builder can now be configured to include only images with certain file extensions
Option to show or hide the mask in the Control Points tab
PTGui optimizer now supports two different methods for handling horizontal line / vertical line control points. 'Level in second pass' first optimizes the panorama using the regular control points and then does a separate leveling step using the line-type control points. This is the method that was always used in previous versions. 'Include in single pass' will do a single optimization pass using all control points. This is the method used by the Panotools optimizer. See the Help page for the Optimizer tab for details.
Align to Grid now gives an error message if the resulting panorama would be wider than 360 degrees or taller than 180 degrees.
Default setting for the maximum number of control points to generate for a project has been increased from 2500 to 8000
PTGui Viewer now supports Firefox in CSS 3D mode too (in case WebGL is not available)
PTGui Viewer: Removed the Full Screen option from the right-click context menu in Flash mode, since this is no longer supported by Flash player. Full screen mode is still accessible through the full screen button at the top right of the displayed panorama, or by double clicking.
Running Align Images for a 360 degree panorama now attempts to preserve the center of the panorama if the images were already roughly aligned. Previously it would choose a random center point.
PTGui for Mac now requires OS X 10.5 or later. Only one version is distributed for Intel 32 and 64 bit support on all OS versions.
Support for full screen mode on Mac: click the arrows at the top right of the window (requires OS X 10.7 or later)
If one of the source images contains a GPS Image Direction EXIF tag, PTGui will include the Image Direction tag in the created panorama (TIFF/JPEG output only)
Added sensor size data for new cameras
Fix: using horizontal line control points for a rectilinear output image did not work properly (since the optimization was in fact done in equirectangular space regardless of the output projection)
Fix: for certain panoramas the optimizer would give up early, resulting in higher than necessary control point errors
Fix: optimizer would fail to optimize certain projects if the initial alignment of the images was too far off
Fix: for 360 degree panoramas, the optimizer would not always keep orphaned images together with the panorama. This caused problems when using Align to Grid with 360 degree panoramas.
Fix: raw files from the Canon 5D mk III would be loaded with a purple tint (fixed in dcraw 9.16)
Fix: certain DNG files would be loaded incorrectly, with black border and vertical stripes (fixed in dcraw 9.16)
Fix: tooltips for the Control point table window were missing
Fix: Convert to Cubic would give 'unsupported file type' error when generating .exr ouput
Fix: When outputting individual layers, a black rectangle could be visible to the right or bottom of the warped image
Fix: Align Images could change the panorama size by 1 or 2 pixels even if Align Images Behaviour was set to not change the panorama size
Fix: When previewing a spherical panorama in QuickTime using the 'eye' button in the Panorama Editor, the generated preview could be limited in tilt such that the nadir and zenith were not visible. This happened if the width of the panorama editor was odd and thus not exactly a 2:1 equirectangular.
Fix: Due to a bug, stitching certain non-360 degree gigapixel panoramas became slower in version 9.1.1. The speed is now improved again.

fix: continuous high CPU load on certain systems
fix: windows: PTGui process would remain running even after exiting the application
fix: batch stitcher hangs while generating control points
fix: adjusting the horizontal field of view slider could cause the red seam lines to disappear in the panorama editor and detail viewer
fix: panorama editor was not updated properly after Undo/Redo of mask editing
fix: changing Blend Priority on Image Parameters tab did not immediately update the display in the panorama editor and detail vieiwer
fix: Assertion Failed could occur when using output cropping (yellow crop lines in the panorama editor)
fix: for certain projects a black or transparent line could be visible at the right hand or bottom of the panorama
fix: Ctrl+clicking (Windows) or Command+clicking in Source Images list did not work correctly
fix: if the project file name contained a period (abc.def.pts), the wrong default panorama filename would be used (abc.jpg instead of abc.def.jpg)
fix: printing the on line help would give error 'no handler found for image type'
fix: visibility of panorama editor window is now remembered when closing and reopening PTGui

New in PTGui Pro 9.0 Beta 3 (Sep 27, 2010)

Panorama Editor and Detail Viewer now have 4 blending modes: Blended, Unblended, Seam Highlighting and Overlay. Overlay is the behaviour of previous versions. Seam Highlighting shows the location of the seam with a red line. Unblended does a hard transition at the seam with no blending.
PTGui Pro: Apply template now copies the mask from the template (can be disabled, see below:)
PTGui Pro: new section in Project Settings tab: Template Behaviour. Determines which part of the project are copied by Apply Template. Can be used for example to create a template which only changes the crop settings
Opening projects now goes much faster
Progress bars during loading and saving of project files
better visibility of bold numbers in Control Points tab
Windows: layout of numbered tabs has been updated to match the Windows 7 style
Both Publish to Website and the QTVR generator now have an option to set the min and max pan and tilt angles automatically, based on the field of view of the panorama
PTGui now remembers if it was running full screen (maximized) the previous time
Detail viewer: navigation with cursor keys, zooming with + and - keys
Detail viewer: added a slider for zooming
Detail viewer: now shows the field of view and magnification factor (compared to the panorama size set in the Create Panorama tab)
'show script' checkbox when stitching using PTStitcherNG
'mouse slow down' feature in Control Points tab can now be disabled in the options
The default output size limit of 20 megapixels for projects created by Align Images has been lifted to 500 megapixels. The default can be overridden in the Project Settings tab.
For linked images (in HDR projects) the masks are now linked as well
mac: user interface performance improvements, in particular when painting in the Mask tab
mac: Cmd+W now closes the active window
When optimizing vignetting and exposure, PTGui Pro now only attempts to detect the camera curve if the project contains multiple exposures (i.e. HDR). For non HDR projects it cannot accurately determine the camera curve so it will use the default curve in that case.
fix: masks were discarded randomly
fix: batch stitcher: right clicking -> Remove Selected Project(s) did not work
fix: painting a straight line in the Mask tab would not always produce a smooth straight line
fix: 'Assertion failed' error when working with HDR source images
