What is FastRawViewer?

FastRawViewer is an extremely fast RAW image viewer that allows the user to see the real RAW-data and the real RAW histogram, and it supports virtually every camera format currently on the market, as well as JPEG and DNG. It opens RAW-files at a rate of about 6-8 frames per second for photographs, or 24-30 frames per second for video (cinema DNG) and it provides you with many useful tools for image analysis, such as per-channel viewing, over- and underexposure areas indication, focus peaking and shadow boosting, as well as using a multitude of preset white balances to view the image, or, if you dislike the presets, creating your own. This program also has propagation, so any changes you make to one image carry over to the following ones, until you tell it to stop. Furthermore, any changes you make to the image are saved in XMP files, which can then be read by Lightroom and Adobe Camera Raw, and used for heavy-duty work.

Very fast, especially if you use jpeg previews (counter-intuitive, I know, but most photographers know their camera jpegs well enough to have a good idea what the RAW offers). Very configurable (remove everything you don't use and FRV looks much better). Very affordable. Uses the Finder to store its sidecar files allowing a photographer to move his edited folders very easily among computers - not database dependent. FRV XMP sidecars can be read by most photo software including Adobe Bridge, Lightroom, DxO PhotoLab, C1, Iridient Developer. Made with love. Best single photo software among them all - means you can depend on the OS and are not tied to some proprietary tool which will eventually be bought out or fail or go subscription.
