FastRawViewer 1.4.7 Release

Big thanks to all of the testers for Technology Preview I and II, your feedback was invaluable.

The new version of FastRawViewer 1.4.7 doesn’t require one to turn on the new features through additional hotkeys, everything is already on.

FastRawViewer. 1.4.7.
  • The changes are as follows:
  • With the new new strategy of processing JPEG representations (both embedded and Lone), opening files has become times faster.
  • Processing RAW data on the GPU: rendering is changed instantly with the change of the rendering parameters (WB, Exposure, Contrast); higher-quality demosaicing is applied to Bayer images (that is, for the vast majority of cameras).
  • The interface rendering speed has also increased somewhat.
  • If you prefer the Windows Explorer / Finder-like behavior for selecting files, you can switch to it.
  • Several bugs have been fixed, many minor improvements have been added.
  • New cameras' support added.

  • Resent copy/move destination lists in menus were damaged after switching 'Single keys act for multiple files' setting.

New features / settings

  • New setting: Preferences - Grid/Filmstrip - Ignore folder paths on selection load (default is off)
  • With this option checked, Menu - Select - Load/Append selection from file will ignore the folder part of the file paths stored in the file that is loaded, so selection load/append will become folder-independent.
  • Preferences - File handling - Reset filtering on selection load
  • With this option on, folder file filtering is turned off while loading/appending file selection. Without that, only visible (not filtered out) files to be selected based on loaded file.
  • Adobe Camera Raw 10.1 compatibility: camera data added.
