Abstract: There are two ways to characterize the morphology of dye cloud: one is the radial distribution of dye around a silver halide grain, which could be generally obtained from a numerical simulation or calculation for dye cloud formation; another is the distribution of projected densities of a dye cloud, which could be experimentally obtained from measurements via scanning of a microdensitometer. An approximate mathematic transformation, suitable for silver halide color imaging system with dispersion couplers, from the radial distribution of dye into the distribution of the relative projected densities has been proposed and derived.
