Abstract

Dynamic range definitions for conventional photographic films emphasize the primary noise mechanisms of such films, namely grain noise. Dynamic range is redefined and noise mechanisms are discussed for photochromic and other grainless films. Measurements indicate peak signal-to-noise ratios in excess of 60 dB for photochromic memories.
