Photophysical Changes in Silver-Silver Chloride Systems

Abstract

In the field of photographic research there appear many puzzling phenomena which in themselves are of interest only as curiosities except insofar as the information which they may yield upon careful investigation leads to a more complete and precise understanding of the fundamental photographic reactions involved in the formation of a latent photographic image and its subsequent development. The action of red polarized light upon certain non-optically sensitized photographic emulsions produces an image which is characterized by polarization and is, in certain cases, photo-adapted so that it appears to be the color of the light by which it was produced. An investigation of this phenomenon in its simplest form was undertaken by the authors in an effort to relate it if possible to accepted photographic theory and to arrive at an explanation which would be more satisfactory than those previously proposed.
