Abstract
We present a set of face-on models of the radiative transfer of stellar light in exponential discs, taking into account absorption and multiple scattering (diffusion) by dust. Attention has been directed towards the effects on the observable photometric properties of different distributions of stars and dust perpendicular to the galactic plane. A realistic model for the arm and interarm regions in the Galaxy, with wavelength-dependent star-to-dust scaleheight ratios, is presented.
