The effect of inclination on observed photometric properties of spiral galaxies are reexamined using a realistic model for the galactic volume emissivity and the dust distribution. The choice of model parameters is based on four well-observed galaxies representing a wide range in bulge-to- disc ratio. The dependence of the isophotal diameter and the mean surface brightness on inclination is found to agree with classical empirical results. Optical as well as near-IR standard aperture photometry of disc- dominated systems is found to be strongly inclination dependent. This could be a serious problem for the IR Tully-Fisher relation. Also, growth curves are found to be inclination dependent, hence modelling of individual galaxies should in general be preferred to empirically determined mean curves of growth.
