Results are presented of photographic surface photometry carried out for 305 (mostly dwarf) galaxies in the Virgo cluster, in which the galaxy images were digitized on 14 of the 67 du Pont plates used for the Virgo cluster survey. Azimuthally averaged surface brightness profiles are shown for all galaxies. The following model-free photometric parameters are derived and listed for each galaxy: total apparent blue magnitude, mean effective radius and surface brightness, and various isophotal radii, ellipticity, and position angle. Most galaxies were fitted by an exponential form and/or a King model profile. The best-fitting parameters, including the 'nuclear' (central residual) magnitudes for dE+dS0 galaxies, are listed.
