User manual

There is a single manual for both Windows and Mac OS X versions (it comes with the installation, too)

How to choose the proper version of FRV

Mac OS X

FastRawViewer for Mac OS X requires any Intel-based Mac (excluding Mac Mini 2005) with Mac OS X 10.6+ installed. We recommend a video card with OpenGL 2.1 support (that's every native Mac video card that works with OS X 10.6). An OpenGL emulator will be used if such a video card is not present in the system; some of the advanced features of FastRawViewer will take significant time to render without hardware support for OpenGL.

FastRawViewer for Windows requires a computer with SSE3-compatible CPU (that is, manufactured after 2004) and not-so-ancient video card. It works on a variety of 32/64 bit Windows platforms: XP, Vista, 7, 8, 8.1 (we suggest Windows 7 or 8.1/64-bit).

FastRawViewer for Windows is available in 2 versions:

  • Graphics based on OpenGL – requires a video card with at least OpenGL 2.1 support.
  • Graphics based on Microsoft DirectX – this version will work with any video card that supports DirectX 9.0 and higher (DirectX 9.0c support or later is recommended)

If your video card is one of the recent (either a discrete one, manufactured after 2006, or a dedicated one, integrated with the AMD/Intel CPU) we suggest to use OpenGL version of FastRawViewer. DirectX version is for older video cards (pre-2006 discrete ones and Intel chipset based). Please see the graphics card compatibility chart, where we list models and names of the chipsets and appropriate FastRawViewer versions.

Windows 7 - Windows 10

Legacy Version (Windows XP - Windows Vista)

If you are experiencing sluggish behavior, or any graphic issues, updating video drivers may be very helpful. In fact, we suggest to keep your video drivers up-to-date in any case.

FastRawViewer 1.0.1 (Build 488)

Changes to Auto Exposure Control

The Auto Exposure indication and the behavior of the program now default to align with Adobe RAW converters (Camera Raw/Lightroom).

New setting Image Display - Apply Adobe hidden exposure correction

If this setting is "on" (default):

  • Exposure correction is aligned with the one that is indicated in Adobe converters (that is Adobe Baseline exposure compensation is added),
  • If the exposure correction is set to zero or is "off", the brightness of the image is aligned to the brightness to the Adobe converters with the exposure correction set to zero.
The setting Keep exposure correction on next file is replaced with the following.

Exposure correction on file open:

  • No correction (default) - if selected, no exposure correction is applied
  • Autoexposure - if selected, Automatic exposure correction is applied
  • Keep from prev. file - if selected, the exposure correction is inherited from the previous file (for the first file in session exposure correction is set to zero).

New setting does not allow to fully emulate the behavior of previous versions for the case if automatic exposure correction for the first file + "keep correction on next" were in use; to handle this, please press Shift-A once in working session (on first file).

Automatic exposure correction logic reworked and enhanced.

New settings in Preferences - Image display

  • for Automatic exposure correction:
    • Fixed exposure shift - if selected, a fixed exposure correction is applied  (Adobe hidden exposure compensation is added to the value)
    • ETTR-style autoexposure (shift histogram to the right) - if selected, the Auto Exposure correction is calculated so that the histogram is shifted to the right.
  • to control the ETTR-style Auto exposure you can set the limit:
    • Unlimited - no limit
    • Hard limit - a hard limit
    • Virtual ISO (default) - soft limit, which depends on the ISO setting at which the image was captured.
Settings for Adobe Exposure Difference are moved from XMP tab to Exposure tab:

Replaced: Use Builtin Adobe/FRV exposure difference when possible and Adobe/FRV exposure difference for other files

With: Image Display - Override Adobe exposure correction to NN EV

Most likely you don't need this setting because all the offsets for the exposure correction between Adobe convertors and FRV for the cameras that are supported by Adobe are already in FRV.

If you want to preserve the legacy ("FRV 1.0" and earlier) behavior, please do the following:

  • Disable Apply Adobe hidden exposure correction
  • Set Exposure correction on file open to Autoexposure or Keep from prev. file

Other changes

  • The setting for Image Zoom on next file is moved to Interface tab
  • For OS X Color Management is enabled by default.
  • The description of the system monitor profile is displayed in Preferences - Color Management.
  • Deleted settings
    • Start in fullscreen
    • Remember maximized window state

    The program now starts with the screen size it had previously. The last size of the program window before going to fullscreen/maximize is stored in the settings.

  • Increase exposure: shortcut Alt+= is added
  • New setting for EXIF display window: Show row labels (enabled by default).

    If it is turned off, only the values from EXIF will be shown and the names (like Shutter, Aperture, etc.) will be omitted. This is intended for the case when only few fields from EXIF are displayed and their meanings are obvious without annotations.
