Abstract

Experimental evidence indicates that a high intensity, short duration exposure produces surface image exclusively in this emulsion. The ensuing fading was shown not to be caused by internal migration of the latent image. The high intensity exposure produced a massive amount of sub image nuclei which could subsequently be rendered developable by a low intensity post exposure. This latensification failed to achieve an improvement in image stability, in that the amount of fading was shown to be solely a function of the density of the fresh exposure. It was hypothesized that although this treatment did raise some grains from an unstable state of developability to stable one, a proportonate amount of grains were brought from undevelopability to one of developable instability. Washing the film in either distilled water or a solution of 5 x 10^-4 N KBr was effective in stabilizing the image against fading.
