I’m trying a new sun effect for Endor?
Thoughts?

I notice that the lighting on the Death star feels too Dark to be realistic. This isn’t a critique of your correction but more an issue that has been present since the film was released.

Here’s my attempt at fixing this issue using the overly dark 4K version as a base, brightening the Death Star highlights more than the rest of the image:

I also toned down the blue slightly and flipped the cruisers so that their highlights matched the lighting of the shot.
