The crystal is digital but the emulsion isn't. Other than CCDs and the 
retina, the emulsion has not a mono layer of receptors and has no defined 
'area per receptor'.
Thus you have a possible superposition of different black-is-on states (= 
developed crystals) for every place in your emulsion, resulting in 
different possible grey shades for every light path through you negative.

I would not call that digital.
