Grain Size Determination and other Applications of the Callier Effect

J. Eggert, A. Kuester

It has been shown that the median grain diameter of a developed photographic layer is a logarithmic function of the ratio of specular to diffuse density (Callier quotient). Also, it is possible from the Callier quotient to evaluate the number of grains per unit area, the mass of silver per unit area, and obtain a value that parallels the graininess of the photographic deposit.
