Well Wavey, I think if I make a tutorial on color correction I'll probably make it more about how to use curves, what to do and what not to do.

When I made my settings for Star Wars, I took lots of screenshots from the movie and pasted them all inside one big image, then I checked what came out when I let photoshop auto-find the RGB mid-curves, and since it seemed to balance the colors more right, I stuck with it and just added my own gamma curve to make the picture brighter and dig up some shadow detail.

Then of course there was the selective color settings, but that's for another tutorial... :)

So anyway, basically I'm saying the tutorial won't be about how I did the Star Wars correction since that was partly done by photoshop. I think I'll do it a bit more about how to make those adjustments yourself, either using some source as reference to match another image to, or how to simply know what to do with an image to get more balanced colors.
