But Star Wars has way less grain than that! Did they use a particularly grainy film in the camera negative?
IB Techs are made a very different way, which has less grain. Also Star Wars is for the most part, a pretty ‘bright’ film, shot with plenty of light, which allows for finer grained film stocks, and the amount of layers in composites are way, way less than in Empire, which had much deeper composites (some of the asteroid scenes went through the optical printer 75 times!), and is for the most part a dark film, shot with less light and grainier stock, and was never released as an IB tech.
There are some finer grain scenes in Empire, but mostly the stage scenes which are better lit.
