Color balance is a pivotal point of the color grading process, which for me is a very important part of visual language and expressivity, in fact much more important than sharpness or optical cleanliness.
The current darktable color balance is still sub-optimal to me, plus it is a remenant of the Lab pipeline, doing masking and blending in Lab while the guts of the module works in RGB.
After the 2 sprints to deliver releases this year (3.2 in August and 3.4 right now), I needed to indulge myself with a color organ allowing me to get exactly the colors I have in my mind while unleashing the power of clean and up-to-date color science.
This week, I developed a new, revised, color balance. I let you with the details and samples, along with the code to test it, on Github :
This is R&D code, so I need a lot of field testing. Thanks in advance and merry Christmas.
PS: I understand this module will be too complicated for most, but there is no other way around. Color is difficult and it’s the only way to achieve the colors I like: soft halftones, beautiful pastels and vibrant primaries, even with inconsistent lights and tricky illuminants.
