We compute the effects of interstellar dust on the photometric properties of disk galaxies in several photographic and photoelectric bands. The solution to the radiative transfer problem including absorption and multiple scattering 0+ light by dust grains is taken from a previous paper by the authors (Magris and Bruzual, this conference). We present magnitudes and colors V. redshift for galaxies seen at different inclination angles and with different values of the optical depth through the plane of the galaxy. The results are compared with those obtained from a straightforward application of the galactic extinction law. It is concluded that in order to properly take into account the effects of dust in the photometric properties of distant galaxies of cosmological interest it is necessary to use correction factors such as those of Magris and Bruzual.
