Stupid film question: Is is the case that all film of a specific type is the same across all formats of that film? For example, is Ilford Delta 100 the same in 35mm, 120, and 4x5?
I ask because I want to do my own push/pull testing and it would be easier to do it on a sheet by sheet basis (4x5) than wasting an entire roll of 120 even though I will use the results from the test to shoot 120 film.
