Oh masking every scene of Jakku would work, but is it worth the trouble for a subtle improvement? To me, not really.
Actually, I’m not sure you know what I mean. With the color mask tool I use, I basically can select certain colors for an entire scene and then easily change them. The test I ran (which I admit is very rough) only took me about two minutes.
Anyway, on to other things — the Han with the dice shot is really looking good. As I’ve said before, I can’t wait to see your finished edit!
