Hi @Bebert, you could read Adding Support for New Raw Formats - RawPedia and How to create DCP color profiles - RawPedia if you want to know more, but perhaps it’s a bit too technical.
In any case, if you want us to improve camera support, the minimal thing you can do is to take the following shots and share them here.
- Completely black (lens-cap on), lowest ISO, aperture irrelevant, shutter speed ~1/10 s
- Completely white (against bright sky for example), lowest ISO, aperture irrelevant, shutter speed (long enough to overexpose, but not more than 0,5 s)
For more refined support, please read the linked articles and provide the mentioned shots as well.
This is true: the raw black and white are a sort-of scaling factors that need to be applied before you can even think about having a properly working DCP profile.
