Abstract

The distributions of development centers in a reduction-sensitized, fine-grained, monodisperse, surface-sensitive dispersion of silver bromide are reported. After the film has been bathed in a gold latensifying solution, followed by arrested development, rather high numbers of small development centers are seen in most grains, even without exposure. After an exposure sufficient to produce latent image in the noalatensified emulsion, the small sensitizer specks are found to have disappeared, and only normal latent-image-development centers are seen. The indication is that reduction, sensitization forms finely divided, sub-developable silver specks, a major function of which is to trap holes or halogen during latent-image formation. Some evidence is given indicating that the larger silver centers are electron traps.
