Poita scanned this same Ep IV print on a professional grade film scanner, but never released anything beyond a few samples. He may have access to the other SE prints too, but if so (as far as I know) they have not yet been scanned.
That reminds me, I’ve been meaning to ask about how exactly the 4k77/80/83 projects were scanned. Over at TheStarWarsTrilogy, the text towards the bottom of the 4k80 page seems to imply that a professional scanner was used.
But from what you’re saying about Poita’s scan using a professional film scanner, am I to infer that’s not what you guys did for the 4k projects?
