Fuji X-T30, X-T5 and a few others show incorrect colors
Closed this issue · 2 comments
The compressed RAWs from the X-T30 and X-T5 (and probably a few more) show wrong colors, the images are purplish/gray. I suspect that the sensor pattern is incorrect, though it may also be a problem in imagepipe or rawler. More investigation is needed, ideally starting by confirming the sensor pattern since that is the easiest to fix if it's wrong.
Note: We use imagepipe for the processing steps like demosaic etc. because it is a lot faster and more efficient than the built-in functions in rawler. We also use a customized fork of rawler because they removed a lot of functionality like color matrix processing and exif rotation handling.
Fixed in v0.4.1 - not perfect because the crop offset is now ignored, but this doesn't affect the image on most modern Fuji cameras.
