The photographs employed in the present investigation have been mainly obtained with the aid of 122-cm and 182-cm reflectors. A PDS microdensitometer was utilized in connection with the digitization of the material. Reductions of the PDS scannings were performed by making use of the Interactive Numerical Mapping Package (INMP), which had been specifically designed for the accurate surface photometry of galaxies. Two S0 galaxies, including NGC404 and NGC524, are studied. The photometric study of NGC404 is influenced by the nearby bright star Beta And. In both galaxies the luminosity profiles present the three distinct characteristics of lenticulars, including the bulge, the lens, and the disk. The obtained results are in very good agreement with those reported by Hodge and Steidl (1976) for NGC524.
