We present accurate optical surface photometry in the U, B, V, R, and I passbands for 11 disk galaxies. The sample has been selected in order to study the different morphological structures present in disk galaxies and includes all morphological types. For each galaxy, we present surface brightness, ellipticity, and position angle radial profiles from ellipse fits to the isophotes. Color index images and color index profiles in U-B, B-V, and B-I are also shown. The photometric information obtained is crucial to understanding the different morphological structures presented in all these galaxies, and to obtain their mass distributions. The latter topic will be the subject of a forthcoming paper. Based on observations made with the Isaac Newton Telescope, operated on the island of La Palma by the Isaac Newton Group in the Spanish Observatorio del Roque de los Muchachos of the Instituto de Astrofísica de Canarias.
