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 7/64-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). The installer will check your DirectX version and offer upgrade if needed.

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.

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 0.9.3

New features and major changes

XMP and other metadata
  • Saving of .rpps-files is now supported (.rpps files are settings for RawPhotoProcessor). New settings :
    • Preferences - Other - Write RPPS files - saves an .rpps file if manual changes of WB/exposure are applied to the image
    • Preferences - Other - Force RPPS files creation - saves an .rpps file with automatic settings for WB/Exposure when a RAW file is opened.

      If a RAW file is moved to a different folder the respective .rpps file is also moved to the same folder.

      To use the .rpps files created in FastRawViewer in RawPhotoProcessor, you need to use the dialogue Import Multiple settings from Menu - Settings. In the dialogue, choose all files in the folder (RAW and .rpps), and the contents of the .rpps-files will be recorded into RPP's History.
  • New setting: XMP - Adobe process version for newly created XMP files. Default: 2012, can be set to 2010 or 2003. Features:
    • If the tag crs:ProcessVersion is set already in XMP file, the version doesn't change and the exposure is written according to the version.
    • If the ProcessVersion tag isn't present in XMP file, then it's added in accordance to the setting (this way, XMP-files created in older versions of FRV and then not changed by ACR/LR will be "upgraded");
    • For 2012 process, Exposure2012 (equal to expo correction in FRV plus Adobe Shift) and the tags Contrast2012, Whites2012, Blacks2012 (set to 0, if these tags are not present in the file) are recorded;
    • For the 2003/2010 processes the tags crs:Exposure, crs:Brightness, and crs:Contrast are recorded (if the file already had the values for those tags, they are preserved, otherwise they are set to 0).
  • New checkmark in the XMP Rating/Label window: Move to next file after Rating is set.

    Does what is written - if the checkmark is checked, then after setting XMP Rating (button in the XMP window, Label menu, hotkeys) FRV browsers to the next file. The behavior of increasing/decreasing the rating (menu, hotkeys) has stayed the same: when using these actions browsing to the next file doesn't happen .
  • New setting XMP - Write photoshop:Urgency tag with color labels (for PhaseOne C1)

    Turns on the recording of the XMP-tag photoshop:Urgency, which is used by CaptureOne to set color labels.

    The setting is activated only if the mode XMP labels is set in 'Color Labels' (this is the default). In other modes, the XMP Labels photoshop:Urgency tag is not modified: if it was in the XMP file, it stays unchanged.
FRV Start/Shutdown
  • New setting in File Handling - Start without filename:In the case of FRV being started up over a particulare file (through any method: drag-n-drop on the icon, clicking on the file, associated with FRV), this setting is, of course, ignored.

    This setting is also ignored in the Single instance mode, if the second FRV copy is started up without selecting the name of a file/folder, then nothing happens.

    • Empty Screen - FRV starts up "without file".
    • Last opened file - opens the top (last) file from the Recent Files list
    • Last visited folder - opens the folder from the list of Recent Folders (from this folder opens either the first file, corresponding to the current file sorting settings, or the last opened, if the 'Remember last opened file in folder' is set)
    • Specified folder - allows you to set a "start folder".
  • New setting Image Display - Restore last View settings on program start

    When closing the program the following image display parameters are saved (independent of the status of the settings):
    • Display mode (RGB, per-channel, BW Conversion)
    • Focus Peaking mode
    • Boost Shadows mode
    • Exposure correction on/off
    • Over/Underexposure display mode

    If 'Restore last View settings' is turned on, then during the next start-up of the program, the above-listed parameters will be in effect.

Browsing files
  • New setting File Handling - File sort order,

    it sets the order of file selection when browsing through the files.

    • Filename, alphabetical - by filename, in alphabetical order, without accounting for letter case, accounting the current localization settings (like with previous FRV versions)
    • Filename, reversed - the order is opposite to the previous.
    • Modification time, newest to oldest - sorts the files by date of creation/last modification of the files, new files in the top of the list
    • Modification time, oldest to newest - the order is opposite to the previous.
    • File type (extension) - files are sorted by extension, files with the same extension are sorted alphabetically.
  • Added Image Display - Auto exposure limit to effective NNN ISO setting.

    The point of it is that the limit of automatic (positive) exposure correction depends on the sensitivity at which the current photo was taken. For instance, if the current file was taken at ISO400, and the auto limit is at 6400 (default value), then the auto-exposure will not brighten the image by more than (6400/400 =) 16 times, or 4 EV.

Small changes

  • Manual exposure adjustment: When manually changing the exposure, rounding occurs to the nearest value that is a multiple of the 'Manual exposure step'.
  • The 'group RAW+JPEG', 'Ignore internal JPEGs', and 'Default image to Display' settings are moved to the separate RAW+JPEG Preferences tab
  • When displaying a single JPEG or RAW file for the cameras where RAW display is not supported, the "current expo correction" field is blank.
  • If for some reason EXIF data cannot be extracted from the RAW file, an attempt is made to extract it from the EXIF data from the embedded JPEG preview.
  • Windows: When using the 'Single Program Instance' the copy of the program which is launched to display the file activates its own window (it is shown on top of other programs and becomes and active application).
  • Statistics table: underexposure statistic is now to the left, overexposure to the right, like it is on the histogram.
  • Windows/DX9: If it works, Windows/DX9 version leaves the record in the Registry confirming that it actually works. Starting with the next version of FRV, the installer will check for the presence of this record, and will not suggest to update DX9 if the record is there.
  • XMP Setting - Write Compact XMP is deleted (the problem that it was meant to solve is of a different nature).
  • Work with formats, for which RAW display is not supported (Foveon): Embedded JPEG 'is displayed instead of RAW'. As a result: - The 'ignore internal JPEGs' and 'do not show internal JPEG if external JPEG is present' settings are ignored - In the RAW+JPEG mode and when an external JPEG is present, the command JPEG rotate causes a change to 'embedded JPEG'

Bugs Fixed

  • Bug fixed: after sleep/awake, the Focus Peaking mode was not restored.
  • "Pink highlights" display has been improved for cameras, which have a true maximum lower than stated (Canon, some copies of Blackmagic)
  • Bug fixed: when moving the last file in a folder to _Rejected, the list of rejected files was cleared, and then irretrievable.
  • Bug fixed: when Preferences were reset the setting for the external program #2 was lost.


  • Bug fixed: If a DNG-files uses a tonal curve, and the DefaultCrop area was selected, the curve would not be applied outside the borders of the Default Crop Area.
  • Old Sony camera display fixed (blown out highlights don't have magenta cast)
  • Exposure EXIF-data: when the file has the ShutterSpeedValue and ExposureTime tags, preference is given to the second (it contains more familier rounding of the values)
  • A series of bugs in the interpretation of DNG-files that come from Adobe DNG Convertor have been fixed (Has to do with, mainly, very old cameras).
