However, none of the previous studies have directly addressed the fundamental question of whether the MG law is in fact suitable for analysis of ideal … WebThe answer, in a word, is amplification. Light causes clusters of silver atoms to form on silver halide microcrystals in a photographic emulsion. These clusters, which may contain as few as three or four silver atoms, catalyze the reduction of all the silver ions in the microcrystals to which they are attached, giving a “gain” of over a ...
