User Manual

FastRawViewer User Manual

There is a single FastRawViewer Manual (in pdf format) for both Windows and Mac OS X versions (the manual comes with the installation, too).

Quick-Start Resources

Use this to acclimate yourself to the interface, tools (RAW histogram and statistics, over- and underexposure indication, focus peaking, exposure correction, white balance, ratings, labels, titles, descriptions etc), Preferences, file handling and navigation, and get an idea as to how to customize the FRV setup for your preferred workflow.

Quick Start Tips

(in .pdf format)

A Quick Start Tour video to help one start comfortably using FastRawViewer immediately after the very first launch.

Workflow Tutorial

Below are several resources that can be used to acquaint oneself with the RAW workflow that we have developed, integrating FastRawViewer into a process that starts at the memory card and goes up to the RAW converter.

They can also help one recognize and analyze operator errors so as to improve shooting discipline.

System Requirements

for Mac OS X

FastRawViewer for Mac OS X requires any Intel-based Mac (excluding very old 2005-2006 models based on 32-bit CPUs:  Core Duo and Core Solo) 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.

for Windows

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, 8.1,10 (we suggest Windows 8.1/64-bit or Windows 10/64-bit).

FastRawViewer for Windows uses hardware graphics acceleration:

  • Graphics based on Microsoft DirectX: DirectX 9.0 is required, DirectX 9.0c support or later is recommended
  • Graphics based on OpenGL - requires a video card with at least OpenGL 2.1 support.

If Your Browsing Speed is Low,

or You are Experiencing Graphics Issues

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.
