In regards to resolution, I think the 30-ish screens that show Oppy on 15/70 are the very, very limited scenario in which a film print can be better in *some* areas, and in my opinion it’s not even “K” related. The full aspect ratio Dune trailer, for example, had significantly more digital noise and compression to my eye than the 15/70mm shots in Oppenheimer. Both were perfectly sharp and not resolution limited, but Oppy’s film print had less image degradation than the rendered file Dune was shown on. We’re really being picky here, because the truth is, any Arri digital camera or 35mm film and up is more than enough resolution for all but the biggest screens in the world.
On the other hand of this coin, is the generation loss of the 5-perf stuff in Oppy - some of which looks great, and some of which is way grainier and muddier than it should be with all the contact printing really losing a good amount of resolution. The black and white scenes especially suffer. I’ll be seeing a standard 70mm showing of Oppenheimer next week, and I’m curious if the 5-perf 65 will look significantly better and match more with the 15-perf shots.
