The Color CurvePosted by J.Corbett
Ok i am getting deeper into color correction. I have been experimenting with curves.
On the top right starts a line that goes to bottom left across the color grid. The top right is the whites and highs and at the bottom left is black and lows. If this is true, then how can i get color to show me the exact point that a particular blue is on this curve. I am trying to over accentuate 3 particular colors.

Color correction does not work that way.
The best introduction to color correction for the impatient is, in my opinion, fxphd's "Digital Color Theory 101" class. I'm not sure whether they're running it this term or not. It's often said that color grading is an art, not a science. This is wrong. It's an art based on a ridiculous amount of science. Trying to grade a shot without understanding the basics of color is like trying to write a novel without knowing the basics of grammar. And James Joyce doesn't count. Everybody keeps insisting that he wrote that way on purpose.
Allen Ginsberg doesn't count either. He was too high on whatever he was smoking...

I agree...to a point. It's is absolutely more art that science IMHO because IME, that is the way I've handled it for 10+ years. Sure...you should know complimentary colors, the difference between indoor tungsten & outdoor daylight, when the idiot freelance cameraman goes from indoor flourescents to outdoor noon sun and forgets to re-white balance and all that...but no job I ever did was based on numbers or any scientific formula. I simply oozed my way around the color wheels, hue / sat & contrasts until I got what I was looking for. You DO have to know when something is just not looking right and when something is corrected...but that comes with experience (and lots of clients saying "ooooo that's frickin' COOL!". It's not a science to me...it's most definitely art. When life gives you dilemmas...make dilemmanade.
So there is no way of sampling the blue and having that sample highlight in the scopes, wheel or curve. I guess i will just keep messing it up till i get it right.

Is it better to work in YCbCr?
I am thinking that tits better to have the luma separate from the chroma. If so....... Then i could adjust luma problems without it effecting the chroma. The problem i am having with this blue is that my luma adjustments are screwing up the color i set. ( CSI Miami Look, super satirated rgb but even luma ) """ What you do with what you have, is more important than what you could do, with what you don't have." > > > Knowledge + Action = Wisdom - J.
