September 30th, 2011New features:
· Spectral Tools - ISO 3664+ : Added a tuning mode where measurements are automatically taken at user-specified time intervals. This mode is particularly useful to tweak the chromaticity of a display.
· Custom RGB space dialog : Added the capability to save the RGB space as an ICC profile; save the profile with an ICC or ICM extension.
Improvements:
· Spectral Tools - Graph : Added text entry fields for user-assigned Sample names.
· Spectral Tools - Graph : Added 3200 K (TV Studio lighting) in the Reference Illuminant menu when selecting 'S1 vs Illum.' or 'S2 vs Illum.'
· Spectral Tools - ISO 3664+ : The chromaticity target interface has been enhanced. The target layout indicates if the measured color is too Red, too Green, or too Blue, and the relative position of out-of-range measurements is now shown around the target.
· Spectral Tools - ISO 3664+ : Added 3200 K (TV Studio lighting) to the Chromaticity and CRI menus.
· Munsell Color Deck : New higher accuracy Munsell database; this database also improves the conversion accuracy towards the Munsell space.
Bug fixes:
· Main screen : The scrollbars' mouse wheel action will not change the Y, R, G, or B value when the scrollbars are disabled. The scrollbars are now hidden when disabled.
· (Mac OS X 10.7-Intel) Due to a compiler bug, the scrollbars' elevator position remains visible when the scrollbars are disabled. To fix the issue, the scrollbars are now hidden when disabled.
· Custom RGB space dialog : Now correctly assigns the illuminant coordinates when computing the XYZ-to-RGB and RGB-to-XYZ matrices for the file obtained with the 'Export to file...' button. The bug happened only for the file obtained with the 'Export to file...' button AND when using an 'Other...' Illuminant that was just changed, i.e. an Illuminant different from the presets (A, C, D50, D65, and E) and different from the previous 'Other' Illuminant. The bug never affected the custom RGB space used in the Main screen as Space #1 or Space #2.
Other:
· Changed the Color Decks database file name to accommodate the new Munsell database. Users who have customized their Color Decks will need to regenerate them.
June 9th, 2010New features:
· The program is now color-managed. The patches color in the main screen and in Spectral Tools are corrected using the default, or user-selected, ICC display profile.
· Spectral Tools - Whiteness : Added a set of tools to measure paper whiteness, brightness, fluorescence, and opacity. There are also tools to check if white and black backings are compliant. Some accessories are required; see the Specifications for more information.
· Spectral Tools - Whiteness : Use this tool to measure color patches with and without UV-cut with only a non-UV-cut Eye-One. A UV-blocking filter is required; see the Specifications for more information.
· Spectral Tools - Metamerism Index : There are now two custom Ambient inputs instead of one.
· Spectral Tools - Metamerism Index : You can save a measured Ambient illuminant to a file and load the illuminant from a file.
· Spectral Tools - ISO 3664+ : You can print well formatted one-page reports which contains information dedicated to compliance reports.
· Spectral Tools - ISO 3664+ : You can load an Ambient spectrum from a file instead of having to measure it.
· Custom RGB space: added the L* (L-star) tone response curve in the preset gamma list.
· Main screen : Additional patch layouts are available when increasing the screen dimensions. Compare color patches on various backgrounds and see how text of each color looks like on black and white backgrounds, as well as on a background of the other color.
· Main screen : The chromaticity diagram is now represented in color to help select a colors with a mouse-click, and the coordinates are shown while moving the mouse over the diagram.
· Main screen : You can select a color on the chromaticity diagram with a mouse left-click or a mouse right-click (ctrl + click on a one-button Mac mouse) and assign the input respectively to one space or the other.
· Main screen : Added the option to show the Planckian locus in the chromaticity diagram.
· Added a Page Setup menu to set the margins, paper size, and paper orientation prior to printing.
Improvements:
· Spectral Tools - Graph : You can save an image at twice the screen resolution for improved quality when printing.
· Spectral Tools - ISO 3664+ : Updated the requirements to those of ISO 3664:2009(E) (essentially, the expected display Luminance is now 160 cd/m2 instead of 100 cd/m2)
· Main screen : The eciRGB 1.0 space has been updated to eciRGB_v2, with a L* (L-star) tone response curve.
· Main screen : You can change the instrument measurement mode with the mouse popup menu.
· The measuring instrument serial number and UV filter information is included in saved files and reports.
· The saved files and reports have been reviewed for presentation uniformity.
Bug fix:
· Will show a warning message and not an error message when trying to save a file which is opened by another application, or locked.
September 1st, 2009· Fixed a problem in XYZ to L*a*b* conversion for very dark colors (L*=8 or smaller). The problem was present in the main CT&A screen only; the problem did not affect the Spectral Tools.
March 12th, 2009New feature:
· Spectral Tools - Graph : Added the capability to measure FLASH light sources (Flash mode).
Improvements:
· Spectral Tools - Graph : The CRI (Color Rendering Index) and the reference illuminant used to compute it are now shown in the Graph tools for Ambient and Flash modes.
Bug fix:
· Fixed the problem where the program would go into an infinite loop with imported Color Decks of less than 20 chips (Note: Custom Color Decks are imported via BabelColor's PatchTool).
May 6th, 2008New features:
· Spectral Tools - Graph : A contextual menu was added to configure the horizontal and vertical graph grids.
· Spectral Tools - Metamerism Index : The reference illuminant for the Color Inconstancy Index (CII) used to be fixed at D65. It is now possible to select among a list of 12 preset illuminants, or select a locally measured ambient illuminant.
Improvements:
· Spectral Tools - ISO 3664 : The brightness uniformity can now be done on up to nine points as per ISO 12646 and the uniformity tool interface has also been improved. Target images for monitor brightness uniformity measurements have been redone; they are included as individual files.
· Spectral Tools - Graph : Finer scaling steps for the graph display.
Bug fix:
· Fixed a computation problem when measuring reflectance samples (with an Eye-One Pro) with an RGB space based on Illuminant E, in the Main screen. The problem did not affect Emission or Ambient measurements in the Main screen, or any measurement type, including Reflectance, in the Spectral tools.
Other:
· New tutorial : Measuring color patches on a display (included in the Help file, in pdf format, which is available as a separate download).
· (Windows) The Color Decks database is now located in the user "Documents" folder, where it can be more easily accessed. As an additional benefit, there is no more a requirement to be a system administrator in Windows XP; this change also makes the program better compliant to Windows Vista security requirements.
· Windows 98 is no longer supported; the last compatible version for this OS is 2.7.1.
December 8th, 2007· (Windows Vista) The drivers and system libraries (DLL) are now fully approved for this OS.
· Fixed the reload of the custom RGB space data when starting the program. This bug was introduced in version 2.7.0.
· (Windows Vista) Windows Vista incorporates a Data Execution Prevention (DEP) feature which monitors how applications access memory. In most Vista Home systems, the DEP setting is set, by default, to check only the system programs and services; in this case, even before the fix, BabelColor CT&A started correctly. However, the DEP setting can be changed by the user, either globally or on a program by program basis, and its default setting may also vary for other OS configurations. BabelColor CT&A did not start when the DEP was assigned to all applications, or to BabelColor CT&A only; this has been fixed.
May 22nd, 2007· A contextual menu was added to most data fields, enabling a copy of all coordinates in a single mouse click. The copied data, in Tab-delimited format, can be pasted in multiple columns within spreadsheets and document tables.
· Because many LCD displays have a natural D60 white point, the D60 Illuminant was added in the selection menus of the Graph Tools and the ISO 3664 Chromaticity measurement.
· The Generic RGB space (ColorSync default space on Mac OS X) was added to the RGB space list.
· Additional selections were added to the display space Options/Preferences setting, and the Generic RGB space is now the proposed default selection for Mac OS X.
· Faster program startup.
· Faster loading of the Color Decks.
· Fixed a data corruption problem when measuring emission data in the Main screen after opening the ISO 3664 tools tab and coming back to the Main screen (Note: there was no corruption when staying in the Main screen or using the other Spectral Tools).
· Changed the Color Decks database format.
April 4th, 2007· Corrected a bug which made the program crash in certain operations when not registered.
June 15th, 2006· spectral graphs (emission, ambient, reflectance),
· density readings and functions (print contrast, trap, etc.),
· illumination evaluation (ISO 3664),
· monitor and ambient Color Temperature (CCT),
· Color Rendering Index (CRI),
· daylight simulator Quality Grade (CIE S 012),
· Metamerism Index (MI),
· Color Inconstancy Index (CII, CIECAT02),
