I’m happy to report I’ve come up with a filter that is very effective at getting rid of that pesky color noise. I really like this regrade, especially considering how awful the bluray looks for this shot (any shot really). The sand looks like sand, and R2-D2 and C-3PO are the way I remember them. 😃
Ps. Note how in the bluray C-3PO is almost the same color as the sand.
