Don’t know too much about .dcp files (for they are not used in dt, which is the only program I’ve been using for raw files). But I guess is more or less the same idea of the video by Aurelien previously posted. But, that’s yet ready to use, most probably, which is comfortable, though Aurelien’s approach gives individualized control using your camera (that can be slightly different fro other similar ones) and even the objective, or exact light conditions.
Anyway, it seems that there is a way of using them in dt, converting them into ICC profiles:
Probably worth trying! I’ll do when I have some time for this, for one of my cameras is supported, and the other is not, but there are other similar that probaly can improve the results.
