Abstract

Photographic image quality can be improved, both in theory and in practice, by the application of chemical techniques. These procedures result in the modification of the transmission or emission characteristics of the original negative. Transmission methods such as physical development increase the effective optical density of the original image by deposition of chemicals at or on the original silver grains. Emission methods such as autoradiography and fluorescence induce an increased optical density image on a new substrate. The information content of the intensified images is often greater than that of the original negative.
