I will NOT be touching up the colors this time from the looks of it, they are beautiful.
There will still be a slight brightness tweak I think, and I might add some sort of sharpening if it doesn't look like crap.
I suggest the last one since the first 2 movies have a nice sharp clarity and the RotJ seems a little softer. I HATE edge enhancement so odds are I'm just talking out of my lower orifice.
