Huh? That makes no sense.
I *think* he wants to know how to use the individual channels to adjust colors in an image. (?) Having learned color myself in subtractive media before the days of computer graphics, I found the additive controls in RGB mode to be thoroughly non-intuitive and confusing when I first switched to digital years ago. It took a few days of fiddling with things to get the concept down, and maybe a few months before it became more intuitive than cmyk. I don’t think a book or tutorial is necessary, but there may be a small learning curve to overcome.
But maybe I missed the point. Sorry alex, maybe the question needs a bit more explanation? 🙂
The old CMYK guys like me and jonf should have no problem with RGB, except for not being able to edit a black channel.
Edit Red to affect Cyan
Edit Green fto affect Magenta
Edit Blue to affect Yellow
…. but (unlike CMYK) when one of the RGB channels is edited, the others can also change (to a lesser degree).
