Sorry, I can’t help with this, plus I don’t have a Fuji camera, but was interested in this as a theoretical problem. I know that Brian Griffith (Iridient X-Transformer) managed to do so because the linear DNG’s his X-Transformer produces can be used in darktable or RawTherapee and give better results in this respect.
Well maybe contact him and ask if he would share the needed informations with us so we could implement it.
DT WB presets also done https://github.com/darktable-org/darktable/pull/1892
Hey there, my first post here…
I made up some dtstyles for the X-T3 (XTrans IV Sensor) Film Simulations. This was my first time doing something like this - so if you find something wrong: Please let me know.
