I’ve noted that in another thread some years ago Trying to figure out RGB (filmic) workflow Boris @s7habo said: “… this is the only thing I still miss in the darktable - especially after using Filmic RGB - a module that can improve and enhance the contrast and details in highlights. This can also be achieved by combining local contrast, contrast equalizer and haze removal, but it is very tedious and not always satisfying”.
Well, that was 5 years ago, but I don’t believe that we since then have gotten any new candy in the candy store that can extinguish this type of cravings … :-), but maybe Boris or others have developed some new method?
