To be honest Dr Dre it looks like you’re trying to give it a modern grade here. It’s crushed, dark and contrasty and the red in his face looks too red.
The 70mm scan just above, although not perfect, looks much more like a film of the era.
I guess that’s why we really need some accurate references of a projected print, because without those, it’s all just guess work, trying to work back from a bootleg recording.
Matching the colors of the 70mm frame is easy, but the problem is, that neither the hues or the contrast are probably accurate to a projected print.
Dr Dre, I feel like you’re making this scene a lot harder than you have too. That 70mm cell seems to have the same “green cast” that the tech scans have. The beauty of this scene is, poor old Tarkin has naturally gray hair. All you have to do is balance the shot out by assigning his hair as grey:
Contrast levels might be another issue, but consider that the white lights are already true white in this shot… the only question is how dark are the darks, but this shot already looks perfectly natural to me. Would you mind matching to my shot and seeing how the rest of the scene looks?
Here’s what this shot looks like on the bootleg:
… and balanced:
So, it’s actually pretty close to your correction. Here are the color matches you requested:
PS I didn’t fix the green in Peter Cushing’s hiar, which is an issue with the bluray colors being crushed together, such that Cushing’s hair and clothes have the same color.
