Image Characteristics in Kodak Bimat Transfer Film Processing II. Image Structure

Paper 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

Strong edge effects, leading to crisp image detail, are found in negatives which are diffusion- transfer-processed by means of Kodak Bimat Transfer Film. The positive images simultaneously formed in the Bimat Transfer Film have soft edges. The sharpness of the positive image can be increased (1) by increasing the physical development rate to promote the deposition of transferred silver on nuclei closest to the emulsion surface of the Bimat Transfer Film, (2) by allowing transfer to occur only until sufficient positive density is formed, and (3) by maintaining a minimum separation between the silver halide layer of the negative and the emulsion layer of the Bimat Transfer Film, such as by restricting the swell of the antiabrasion overcoat of the negative.
