Curves Luma does not always work?
Posted: Fri Mar 20, 2020 1:01 pmHey everyone.
Often, when I start a grade, I'll desaturate a node, and then go into curves to set my contrasts. I find that often, if I select the luma (Y) only, and start fiddling with that, nothing happens, no adjustments are made. If I link RGB again, then I can adjust. Same thing with the values under the color bars/wheels. Adjusting luma does nothing to the image.
I suspect that this is by design, and I was hoping that someone perhaps could help me understand what I am failing to understand.
Here is a reference of what I'm trying to do:
In advance, thanks!
