Optimization of the optical granularity measurement conditions of model photographic layers

Computer results of the model dependence of the measured optical granularit y on the area of the measuring aperture are presented. The optical granular ity is expressed as a standard deviation of the optical density fluctuation s. A spherical shape of the silver grains was assumed in the theoretical mo del of the developed photographic layer. The microdensitometric measurement s were simulated assuming various conditions. This model and the results ob tained are intended to help to further develop an integrated simulation sys tem for research on the structurometric properties of silver-halide photogr aphic layers.
