The camf matrix used is named CamToXYZ_Flash... (also for SD9/10/DP1)

Hi, I am happy to see people doing what you are doing. I myself tried much doing it; unfortunately I have not much time right now. Maybe a single thing: you probably don't have to expect building ready-to-use sRGB values. Most certainly, matrices from the X3F files give pictures in XYZ colorspace (CamToXYZ). Such a colorspace is the most convenient for white balance correction; you can then easely convert from XYZ to sRGB, but you have to remember that sRGB has its own illuminant (which is D65). If the illuminant for your XYZ picture is not D65, you have to perform some chromatic adaptation to D65 before converting to sRGB. See (section "Math"). Regards.
