I believe that the blu-ray was color graded on a shot by shot basis and then a blanket yellow tint was added on top over the whole film. I have just removed the blanket yellow tint and left the shot by shot colour grading underneath intact. You may think that methodology is flawed but to my eyes that is not the case and I see a lot of flaws in your own methodology which I’ve pointed out earlier, the unnatural looking fleshtones in particular which is a very big problem, the biggest a release can have as far as i’m concerned.
Colour matches would perhaps only be worthwhile in my opinion if you had a 35mm frame of every single shot in the film to match to, and even then, trying to force the colours of the blu-ray to match the very different colours of the 35mm LPP gives very questionable results to my eyes, for it to work the colours and image dynamics have to be 100% identical. This shot below for example of the Bluray matched to the 35mm LPP, the fleshtones just look wrong to me, they don’t look right relative to the lighting of the scene and the overall colours. The 35mm LPP frame looks fine, but the Bluray matched to 35mm LPP does not IHMO, like you’re trying to force two completely different colour schemes and image dynamics together and ended up with a bit of a mishmash where the colours don’t interact correctly:
We both have our own methodologies that we prefer and that’s fine. I see numerous problems with yours, you see numerous problems with mine. I don’t think we’re going to be able to convince each other of the merits or problems of our own methodologies, the only way to proceed would be to compare two releases of the same film created using the two different methodologies. I would personally find that fascinating.
The main difference between you and me of course is that I have actually commited and put out a release of Raiders of the Lost Ark. You put out your release of Raiders of the Lost Ark using your colour matching methodology, then I’ll watch the whole film in full, as its meant to be seen. The only way of truely accessing a regrade is watching it, not nitpicking single screencaps. Then I’ll be happy to discuss with you the merits and flaws of each release and the respective methodologies used to create them. Until then, I don’t see there being much point discussing this further.
You should check out my release in motion and see whether that changes your mind about the colours. One thing i’ve learned from creating regrades is that screencaps very often don’t tell the whole story, you have to watch the actual release in motion.
