So, I finally found some time to make my own icc profiles for the RX100, using RawDigger and the MakeInputICC wrapper. However, I can't seem to make cLUT profiles that are of any use, so I have to stick to using the gamma + matrix profiles. They come out neutral but then you can't use the colour editor in C1. I also tried working from the default C1 profile and tweak it in colour editor to produce an icc this way, but I still haven't been able to figure out a successful universal correction recipe this way. Ultimately, I tend to choose the custom-made profiles and forgo the advanced colour correction, which is a pity because it's a more powerful tool than what you get with LR. Oh, well, at least you can control WB, Saturation, Levels and Curves to affect your global colours this way. It'd be great if curves rgb adjustments could be applied locally...
