The results of photographic surface photometry of late-type spiral galaxies in the clusters Abell 426, Abell 1367, and Abell 2151 are presented. U- and R-band surface brightness profile properties are analyzed in terms of the following environmental parameters: the projected distance from cluster center, the projected distance to the nearest neighbor, and the local projected galaxy density. No significant correlation is seen between the structure of the galaxies and the projected distance from cluster center. The most pronounced correlation found was with the projected galaxy density; both the isophotal radius and the slope of the disk brightness profiles are affected, and the color profile may be affected. These influences may be attributed to environmental processes: ram pressure stripping of the galaxy gas by the intracluster medium and tidal stripping of the stellar material by the prolonged exposure to the gravitational field of subclusters.
