I have to ask, How many times we had this topic already? (Under different names).
And once again, i am reading some of the posts and they are EXACTLY the same posts but in different words in which we had in previous topics of this subject.
Even poor Troy Sobotka is probably tired of replying to the same things after covering them endless times.
Try this : Blender Support for ACES (Academy Color Encoding System)
Enough reading material for a week (it covers THE SAME points brought up).
