Calculation of light-scattering properties of spheres is a well known technique, that nowadays can easily be done on any personal computer with available programs. In the photographic field, such kind of data may be used to calculate the diffusion of light in a photographic layer, e.g. by a Monte-Carlo procedure. The extension of such calculations to other particle shapes was practically impossible up to recent times. Meanwhile efficient models and corresponding software have been developed that enable "good" approximative solutions of Maxwells Equations for more general shapes, though an amount of computing power exceeding that of a normal PC is usually required. The paper will present results of light scattering calculations for tabular silver halide crystals with different aspect ratios and will discuss some consequences regarding the diffusion of light in simple photographic layers containing such AgX-grains.
