Adobe has released Lightroom 6.4. Many of the interesting changes are the same that we covered with the detail article on Adobe Camera Raw 9.4 - see here.

Now let's see the changes for Lightroom in details, as new features/improvements and bug fixes.


  • Faster update of thumbnails when editing multiple images using sync or copy&paste, also Lightroom now builds 1:1 previews in advance to be ready for fast zooming in.
  • The panorama merging process is about twice faster than version 6.3.

Additional features / improvements

  • A new interesting boundary warp feature to make a rectangular image of a merged panoramas with irregular borders - see the ACR 9.4 article for description (link here).
  • New cameras support and many many new lens supported - again all details in the ACR 9.4 article (link here).
  • Improved quality when applying Auto Straighten and Upright “Level” mode.
  • Metadata is added to merged panoramas to support Photoshop’s Adaptive Wide Angle filter.
  • When adding photos through Lightroom mobile or via Web, user can set the location and folder structure (option in Preferences > Lightroom mobile).
  • Added paths to Home, Documents, Pictures and Movies/Videos folders to the choice of destination in the Export dialog.
  • On Mac scrolling photos with a Magic Mouse, trackpad or other similar device, the scroll can be too fast: there is a new option in Preferences > Interface to disable "speed swiping”.
  • Nikon 1 J4 Camera matching profile support added.
  • Added support for tethering for following cameras:
    • Nikon D5500
    • Nikon D7200
      Supported Nikon cameras are working again on Mac 10.11 El Capitan, while tethering Leica cameras on Mac 10.11 El Capitan is still not working - Adobe is waiting for a Leica update.
