Abstract
A physical transmission meter was built in which both the diffuse and the specular transmission of a film sample could be measured successively at the same point on the film. Q factors computed from these data are plotted as functions of the diffuse density. No base nor minimum density correction is made and hence the computed Q factors are effective rather than absolute values. A few examples are given showing the result of making such base density corrections. Data are given on a wide range of both picture and sound negative and positive materials. In each case, phototubes and filters were selected to simulate the effective range of spectral light used in the practical usage of the material.
