Remembering back to my film school days…
There is no "resolution" to a frame of film. Each frame of film has, in theory,
an infinite resolution. This is not the case in reality, however, due to the
grain of the silver particles within the film stock. Calculating this can be
difficult, though, as each film stock has a different gain pattern and granule
size.
The upshoot to all this… if you are recording to 35mm film, you will probable
stop seeing the benifit of higher resolutions somewhere between 8Kx8K and
12kx12k. If you are rendering to 4×5 film stock, You will probably never be
able to hit a resolution where your pixels are as small as or smaller than the
grain of the film.
