The Reliability of Bleaching Techniques for the Determination of Latent Image Distribution in Silver Bromide and Iodobromide Emulsions^*

* Comrnunication No. 2196H from the Kodak Research Laboratories

Abstract

The reliability of various bleaching Techniques was studied on the basis that a bleach should destroy surface latent image compleldy and that the internal speed should be independent of the precise bleaching conditions ond be as high as possible. Only two treatments satisfied these conditions. These were a potassium-ferricyanide-phenosafranine bleach and a silver-dichramale bleach ofter a washing treatment.
