Is this using the film scanner you recently bought?
I scanned these frames several years ago on a scanner in the art department of a college, used specifically for photography and film scanning. I expect that if the colors were significantly inaccurate, it wouldn’t have been much good for those things. I only know that under close visual examination in the photo lab using a magnifying glass, the colors of the frames seemed to match fairly well what I got out of the scanner.
And certain frames seemed to look quite good to me, such as the Vader shot and R2. Sure, they may look more vibrant when projected in a theater, but to me the Death Star shots I have seen contain a lot of color variability. It seems doubtful that a calibration problem would faithfully represent the colors of one Death Star interior and not another. Granted, I only have a few hundred frames for reference, so you would be a better judge of consistency, especially in the first two reels. If you discover that they do indeed contain a consistent yellow tint, that would mean a bit more work for my project, which is why I want to be absolutely sure 😉
I now have about 2,500 frames representing roughly 500 shots, with more underway. So, this should provide a pretty good idea of the colors of this particular print. 😃 The yellow tones are indeed very consistent in the second an third reel from what I can see, but it will be interesting to see the consistency or lack thereof, once they’ve been put in sequence. It’s great to look at the frames individually as they arrive in the mail, but as Obi-Wan said: your eyes can decieve you, don’t trust them. 😉
