Yeah, I like it a lot. I’ve used other viewers but this one gets my vote, since now I can get rid of all the junk right from the CF card. I toggle the fullscreen mode using the “F” key, and to compare exposures you can close all windows but the histogram and keep the bottom bar; then use the “tab” key to switch between no windows and just the bottom bar and histogram. Also, to compare two images side-by-side, you can always launch 2 instances of FastRawViewer.
@buddingphotographer my bad for the broken link 🙂
