While playing with a few commercial image editors on Windows, I noticed that the last set of LUTs had a huge bug and mapped black to dark grey. This looked truly awful!
In trying to debug this issue, I noticed an error in my thinking: I had indexed and mapped RGB values slightly incorrectly in the LUT, resulting in incorrect mappings. Here is a new set of LUTs that corrects both of these issues: Fuji LUTs V8.zip (53.3 KB)
Colors match much better now, with the remaining differences usually coming down to differences in white balance and contrast processing.
