Hey all. I was wondering if anybody knew of a way to achieve the outcome of a Luma vs Sat curve similar to the one here in Resolve: 
Basically when color grading, when I change the color of the darks, it also affects the shadows. The Luma VS Sat curve can crush the shadows back to black without changing the new dark tone I created.
Anybody know of a way to do this in VEGAS or any 3rd party plugins that can achieve this?
The Graide Color Curves plug-in for Vegas Pro offers this (and many more).
Awesome. Know of any others? I'd like to see as many options as possible before purchasing.
Not a curves tool but a comprehensive collection of color correction tools is DFT (Digital Film Tools) available as OFX which works fine in Vegas Pro. One tool (among a hundred others) of it is "Ozone" which lets you color correct a video based on 10 different zones which you can pull from either luma, hue, saturation, average or the six color channels and then individually color correct.

Sounds like Ansel Adams elevated to the digital constellation.
I also found a similar free option, http://aav6cc.blogspot.com/ , (granted it's 10 years old) that works very well similar to DFT. These are great tools to have in the arsenal but still would like it if more companies created the Luma vs Sat Curve
