New in Visual Similarity Duplicate Image Finder 6.2.0.1 (Feb 10, 2016)

  • Visual Similarity Duplicate Image Finder 6.2.0.1 Provides Flexibility In The Folders List And Can Automatically Adjust The Orientation Of The Preview Images.
  • The duplicate photo finder tool is already flexible with plenty of filtering options and duplicate search algorithms, but this new release adds some extra flexibility by providing an easy way of altering the “Exclude from auto-check”, “Disable self-scan” and “Remove from list” by providing a context menu which operates on all the currently selected items.
  • The new option “Automatically adjust preview images orientation” is located in the settings and tells the application to use the EXIF image information to properly preview an image by automatically rotating the image. Such option will not work on images generated by old camera models that do not have sensor for camera orientation or on images that have their EXIF meta-data removed. Of course such images can be manually rotated using an external tool in order to face the desired direction.
  • A user interface fix addresses a rare issue that is present when using “Large fonts” and low resolution and causes the folders panel to disappear. A fix for the duplicates information above the duplicates list is also available. The information was not properly updated after using the “Image Search” feature.

New in Visual Similarity Duplicate Image Finder 6.1.0.1 (Sep 7, 2015)

  • Added results grid menu item 'Remove from List' which only removes the selected items from list, but doesn't delete the files

  • Changed 'Delete...' menu item shortcut to Shift+Del and 'Remove from List' shortcut to Del
  • 'After scan' combobox is now enabled during scan
  • Fixed: Multiple images preview wasn't updated with the first found group after scan is complete.
  • Fixed: Loading shell associated icons in results grid if OS small icon size is different from 16x16 pixels

New in Visual Similarity Duplicate Image Finder 6.0.0.1 (Apr 6, 2015)

  • Find Similar And Duplicate EXIF Tags:
  • The new scan method makes it possible to find and group together photos that have similar and duplicate EXIF Tags. The ways this feature can be used are limitless as it works on all the available EXIF Tags. While the most common use would be to search for similar and duplicate comments or descriptions the feature may also be used to search for duplicate camera model in order to find all the photos shot with a certain type of equipment. Searching for duplicate EXIF Date can reveal all the photos from e certain photo shootout.
  • Preview Multiple Duplicate Photos Simultaneously:
  • This release includes a new preview panel that lists all the duplicate photos in a group together. The panel can be resized to order the thumbnails in a single or multiple rows and the thumbnail size can be altered using the mouse wheel. The thumbnails also include a check-box in order to denote the photo’s checked state and also can be used to toggle that state.
  • In some cases it may be more convenient to preview two images at a time so the old preview panel is preserved in the new release. It can still be used if one prefers to see a larger preview of the selected items.
  • An improvement now automatically adjusts the orientation of the previewed image if such information exists in the EXIF data.
  • New Duplicate Photo Finder Features:
  • There are plenty of new features and improvements in this release. Some of the more important ones is the fact that the EXIF tags list is now sorted by tag name by default and the sort order can be reversed by clicking the column title.
  • DICOM tags – files used in the medical industry are now supported in the Corporate version of the tool.
  • Another improvement now makes it possible to preserve the order of the duplicate groups for multiple save/load sessions. This is especially handy while working with large projects where a user analyses a bunch of groups and wishes to continue later with the rest.
