Image Characteristics in Kodak Bimat Transfer Film Processing I. Grain Structure

Presented at a Symposium on Processing Technology organized by the Science Committee of the Royal Photographic Society on 12-14 May 1965, in London.

Abstract

In the diffusion-transfer processing of negatives by means of Kodak Bimat Transfer Film, a moderately high-speed negative film shows a granularity equal to or greater than the granularity given by conventional development to an equivalent contrast. The filaments of the individual grains are thickened by solution physical development, increasingly so as the image density is increased. The positive image simultaneously formed in the Bimat Transfer Film has about half the granularity of the negative, and the silver particles have the appearance of rough spheroids. Marked differences in silver distribution occur in the use of two selected solvent-containing developers (Bimat imbibants).
