We present the redshift and photometric data of a survey for intrinsically faint galaxies towards three nearby voids and the Hercules supercluster. The project is aimed at finding galaxies of absolute faint magnitudes or of low surface brightness within these voids. The selection of the voids and the search strategy for the galaxies are outlined. B and R magnitudes, major and minor diameters, as well as the morphology are determined. The diameter distribution of the galaxies is discussed. Optically measured redshifts of 174 galaxies are given. Most of the galaxies found show emission lines and late-type morphology. Several have low-surface brightness features. Our survey identified a higher percentage of nearby galaxies than magnitude or diameter limited surveys.
