It would depend a lot on the film used. Yes, digital definitely has the edge
in ease of use and as the quality increases it will replace other formats.
But, if you can scan 35mm slides at 4000 ppi and not see grain (with
particularly fine grained emulsions) then you can scan a 4x5 at 4000 ppi and
not see grain either (assuming it's the same emulsion). That's going to give
you a 16000 x 20000 image or 320MP. I'm not sure what resolution scan is
needed to see the grain in the finest grained emulsions.
