 In the case of large format, 4 x 5 inch films can record approximately 298.7 million pixels, and 1,200 million pixels in the case of 8 x 10 inch film.However, as with a digital system, poor optical quality of lenses will decrease the resolving potential of a film emulsion.Shot noise, produced by spontaneous fluctuations in detected photocurrents, degrades darker areas of electronic images with random variations of pixel color and brightness.
