Having re-examined my reference materials, I’ve concluded there’s something wrong with the Tarkin/Motti color grading. The Tarkin frame for example looked like this:
…and should look closer to this (preliminary):
Just thinking out loud:
You’re trying to get some of the “warmth” back (which is good)… When I look at a lot of these correction threads I see very similar results… pulling the blue/magenta out of the blu ray gets us something a bit cold and when white balanced tends to push towards greens in some of the highlights. Looking at photos like this though and the Tech-Preview I see a lot more “peach” in the skin tones that seems to be really hard to get at from the blu ray. It almost feels like the film should have a mild orange/yellow push in it’s grading which looks more in line with some of your 70mm regraded shots before you white balance them.
