![]() Hue preserving tone mapping is pretty much always desirable. This has been supported by color science research (see:, and ). The direction (increase vs decrease) of saturation correction depends on what tone mapping operation you are using. and after being presented the options we always settle on a tone mapping that sacrifices some saturation for lightness. I have tested this quite a bit over the years with multiple colorists, DPs, etc. Tone mapping is about making tradeoffs in multiple dimensions of color appearance, and sacrificing some saturation allows you to better maintain the local relationship between colors as well as image detail in highlights. Generally speaking, it is advisable not to preserve all the saturation when performing tone mapping. I think there are 2 key differences:Ĭlick to expand.I'll offer some pointers from my experience. I agree with you that the DaVinci Resolve image looks better in this case than madVR's tone mapping. Of course a custom tailored curve for one specific movie has a good chance of beating a default curve which tries to look decent for all movies. So I have to find a good tone mapping curve which looks decent with all kinds of different material. They will want to use one setting for all movies. Which is not what madVR users will want to do. But again, there's a good chance the guy doing the encoding manually adjusted things. This is an area we will be working on here in the upcoming weeks. ![]() This is not something I should do automatically, IMHO, because it would make some movies look under-saturated then.Ģ) I think DaVince Resolve probably uses a different tone mapping curve which helps with the face details/shadows. I'm very careful to not change the saturation at all (except for rare overbright pixels)! The guy doing the DaVinci encode must have manually lowered saturation. I think there are 2 key differences:ġ) The DaVinci Resolve image has lower saturation. ![]() Click to expand.I agree with you that the DaVinci Resolve image looks better in this case than madVR's tone mapping. ![]()
