Ive been confused about the aspect ratios used in 35mm film compared with aspect ratios on digital. The first one I was wondering about is Panavision or 2.35:1, I know that on 35mm film using anamorphic lenses you are actually squeezing more light onto the 35mm (4:3) frame thus the horizontal “squeezed” image and then either digitally stretch in out or optically with the projector to regain the original 2.35 size. There is no cropping on this format when dealing with film. When it comes to digital 2k+ like REDs or their higher end counterparts… Is this real anamorphic achievable using a type of anamorphic lenses? or do you just capture at 2k or such and just crop the image to a 2.35:1 aspect ratio? If cropping is the case…then isn’t this destructive and worse than film?
Or is there a way to capture at 2.35 like film without resorting to a mattbox or other method that removes part of the image?
