It sounded crazy to me that Dune was shot on digital cameras, converted to analogue film and then digitalized again. It doesn't really make sense in theory, but I loved the end result in IMAX, it felt different to other movies.
EDIT: Now that I've read up on Greig Fraser's reasoning, it makes a lot more sense for Dune! https://ymcinema.com/2021/12/03/dune-was-shot-on-alexa-lf-tr...
Yes. They did that because they didn't have digital equipment suitable for cameras and projectors. This is much crazier.
