AskMeCha... Photoshop tutorials. Where do people recommend I go for some good ones?→[More:] I like Deviant Art's tutorials, when I find a good one, but I hate their interface.

What I want to do (as one example) is find an easy way to take, say, three pictures and have the two that I'm pasting into the background have the same lighting levels and colours as the background. I can *sorta* do it by eyeballing the levels in all three pics and adjusting them and the colours to match up, I just think there must be an easier and effective way to do it.

There are other things I'd like to do, but I'm just wondering where people go to bone up on things they've forgotten, or would like to learn.
