"analog" stuff
The 35mm film is only 1 bit per "pixel". (a "pixel" being a film grain spot that suddenly changes when hit by a number of photons in rapid succession) It is this property that makes resolution highly misleading. The film is naturally dithered. A digital setup with similar resolution would presumably have far more bits per pixel. So the film sounds better than it really is.

The eye is similar, but it also averages over time. The retina uses pulse modulation, from a high of about 1 kHz down to wherever the noise floor is... probably below 1 Hz. The longer you stare at something, the better you can sense the detail and the color.
