We present preliminary results about V and R photometry of more than 1500 galaxies that belong to a sample of 30 Abell clusters. We have used both the r1/4 and the exponential laws in order to account for the luminosity profile of the galaxies. We have also used the Sérsic´s law as an alternative approach. The goal of this work is to investigate the dependence of the photometric parameters of the galaxies with the projected local density and the global properties of the involved clusters.
