Hmm, well, I've seen a few different color correction jobs, like the pics above, and on adywan's threads, and of course, I've seen SW: Revisited.
I really like the concept behind it. It shows a LOT more detail, and everything is very crisp and clear.
But then... sometimes, it can seem to be just slightly too... much. Er... well, I guess, what I mean is, too little. lol
I think that color correction is absolutely necesarry from the 2004 DVD edition, especially... (blue Yoda does not work. lol) But at the same time, just make sure you don't take out TOO much color. There should be a slight natural tint there, very slight. You know what I mean?
