Abstract

Methods have been evolved for determining optical density, silver content, the modulation transfer function and the granularity of the elementary layers of a photographic emulsion coating. Preliminary data are presented. From the distribution in depth of the density, the distribution of inner exposure can be derived; this has a maximum a little below the surface. The modulation transfer function is more strongly degraded the lower the elementary layer. The power spectrum of granularity shows a relatively high contribution by the lower elementary layers for low spatial frequencies.
