Right, but my understanding is that most grain is in the camera negative because it had to be shot at 24fps (or up to 120fps for slow motion), whereas later generations were duped using more sensitive film?

Like with like:

For the benefit of the forum, I understand poita’s Empire scans were done using state of the art equipment that introduces virtually no “scanner noise”. The “blue-yellow” grain in particular is far higher than is visible on Star Wars. I’m curious as to whether it really represents how the Kodak stock looked in 1980 or whether the grain has accentuated itself over time?
