I'm starting in digital paint and I cant figure if it would be better to work in a 16 or 32 floating point bit rate depth, or even neither?
I've noticed that working in a floating point precision is important for HDR paint, but apart from it I'm still not sure if there exist any advantage. And most importantly, any advantage in sRGB color space work.
This discussion was somewhat vague as I myself had near zero experience with digital painting.
Particularly by being "transparent" about how things are done Krita works in a way completely different from Photoshop (and it is good, you get to learn a lot! Maybe it will cut a lot of work needed to get familiar with weird color mixing and "magic").
Particularly I answered a question about painting here that can answer a lot of doubts:
Going to the point... 16 bits may matter (and some editors may hide it from you), linear color spaces can be really great and they need 16 bit, also it produces much less banding due to math on smudging paint methods to mimic wet techniques. But clearly it mostly depends on the result you expect while painting.
