A Reaction-Diffusion System

Part of the Mathematics in Industry book series (MATHINDUSTRY, volume 3)


In development the film is immersed in an aqueous solution as shown schematically in Fig. 16.1 which, for simplicity, depicts a three-layer film. The emulsion layers contain silver halide grains and oil droplets. The oil droplets contain chemicals — couplers — that form dye and inhibitor in the course of development.
