Best method for lowering red saturation
90% of the time that I spend on post is dealing with oversaturated reds. I shoot in V Log. When I bring the clips into Resolve, I will do color correction, adjust contrast and color saturation. By the time I get the saturation at a nice point, my reds, most notable in my skin tones, is too saturated. I then have to spend copious minutes tweaking this setting or that, which affects the red level in the whole clip, naturally. Outside of qualifying my skin (which is a bitch with my beard and all) is there a tool in Resolve for raising or lowering strictly the red, blue or green levels without affecting to much of the rest of the image?

Hue versus saturation curve is the key.

Hi Duke
Do you start with a v-log to rec. 709 lut ?
-
No, I will either manually adjust black and highlight levels using the custom curve and then increase saturation (Yes, I’m starting with V Log), in which case my face will get more saturated than the surroundings, or else I’ll just immediately apply a LUT I created which almost always gives me the look I’m going for, but which also will over saturate my face. I’ve desaturated to where I want it and created a new LUT, but when I apply it, my skin is still too red.

Yes, I’ve used that. That’s the best method? That was my reason for asking.

There are a lot of techniques for doing one thing in Resolve. You might need to use multiple tools/techniques to get the result you want.

What happens if you use a Red Hue vs. Sat curve? That’s generally what I do, and it’s a lot more gentle than a key per se. If necessary, you can use a tracking window on the person and only affect reds within the window.Sometimes, a targeted Custom Curve can do it, as with choosing the Red-only curve and making an adjustment there. There’s a lot of “it depends” to this.

I’ve tried that, Marc, but it affects the overall image, in my case, anyway. Hue vs. Sat seems to be the easiest way to go for me. Remember, I do this for a hobby. For me, easier is better. Thanks for responding, guys. Cheers!

I did mention using a window, right?
-
Yeah, but here’s the problem with windows (or face tracking or anything else meant to isolate). My “takes” are anywhere from 2 to 8 minutes long, and I move around a lot. Again, my stuff is nothing like what you guys work with, scenes that are a few seconds long with little movement (as far as actors). I think I shoot more for having something to play with in Resolve than anything else. You won’t be seeing anything of worth from me, unfortunately. But again, I can’t tell you how much I appreciate guys like you and all the others who know I’m a hack amateur and still take the time to help. Cheers!

There’s always a solution. Make a bigger window that doesn’t necessarily get tracked. Or qualify a fairly broad key and just desaturate a little bit (either with a curve or with overall chroma, your choice). There’s always a solution… it’s a question of how much work you want to do to get there. Me, I just roll up my sleeves and say, “OK… we’re gonna do this right.” Boom, job done… move on to the next thing.
