Abstract
After briefly referring to the effect of the scattering of light upon measurements of density, according to the way in which density is measured, the author alludes to various attempts made in the past to find a quantitative relation between the specular density and the diffuse density of a medium. A special projection densitometer was designed for measuring the specular density, and a form of integrating densitometer for the diffuse density, of a number of samples of negative and positive motion picture film. The results indicate an exponential relation between the two kinds of density, the time of development and the variation of gamma, within the range of the measurements, being negligible.
