Color Boost vs “Sat Vs Sat” Curve

[Toby Tomkins]

Color boost is the devil’s work. That’s why.

What are you trying to do? Sounds like you’re comparing tools. Just use the tools that works best for what you are trying to achieve.

If you want to throw another method into the mix, try using the HSL keyer with only an ‘S’ (saturation) selection and manipulating that. I advise a soft selection.

The software developers at BM and the original developers at DaVinci, have given us an entire pallet of tools that perform many similar functions that work in very different ways to achieve different results depending on the task at hand. Many of the tools have very subtle differences in their programmed behaviors, while other tools are fed less subtle and easier to interpret visually. If you spend the dough to get Alexis Van Hurkman’s in-depth training from Ripple Training he takes you through virtually every tool in the Resolve toolset, and he explains and shows you how each of different tools is programmed to accomplish different tasks you may encounter in your role as colorist.

FYI, since Alexis writes the Resolve manual for Blackmagic, you’ll have a hard time finding a better source of info about the toolset in Resolve.

I love the fact that there are numerous ways to manipulate saturation. CB is often best for landscapes in my experience as it bring subtle things out of a scene without going “Chocolate Box”. Indeed sometime I boost CB and drop Sat.

I find the behaviour similar to Vivid and Sat in Photoshop.

Toby,

I’m using DaVinci Resolve for about half a year and keep learning that many of Davinci’s tools sometimes are very useful and not as simple as they might seem.

For example, recently I’ve discovered that Highlights and Shadows controls besides rising and lowering of highlights and shadows are incresing and dicreasing midtone contrast in areas applied too. Never used them before. But now I’m using them a lot! Probably I would never know it without testing on different greyscale and color charts, because the difference from let’s say rgb curves is very subtle and decription in manual is quite vague sometimes:)

That’s why I try to get as in-depth info about DaVinci’s tools as I can.

I’ve never used Color Boost before cause I find that it makes the image too oversaturated, but maybe I’m applying it the wrong way?

Btw, DaVinci’s HSL keyer is brilliant but it takes some time to make proper mask. So the more I can do in primary correction the better.

-respectfully
