What are RGB curves and how do you work with them?


Recommended Posts

Hello, in a lot of tutorials I've seen people talk about "setting your curves" or colors to pictures. I'm just wondering how you work with the RGB curves and how you get the color or colors you want out of it.

Thanks!

Ok thanks, I read it.

I'm having trouble getting one color though. I'm trying to get green and purple on an image...

What I don't understand is that when you put a green point on the graph, the picture doesn't show any sign of becoming more green; it actually turns more purple.

What I'm asking is how do you manipulate the graph to make different colors?

Can someone elaborate the math stuff behind that?

What means the axes?

Reposting, I was hidden between two big screenshots.

No. Way. I've just seen Bob. And... *poof!*—just like that—he disappears into the mist again. ~Helio
