The analysis of 82 V and 43 B CCD frames of disk CGCG galaxies in the Coma and Hercules Supercluster region is presented. These observations represent the first step toward the completion of a CCD survey of all spiral galaxies in this region, but by themselves they do not form a complete sample. Morphology, diameters, magnitudes at the 25th mag/sq arcsec isophote are determined. V band light profiles and two-color surface photometry (when available) are presented. The light concentration indices of the studied galaxies are found to correlate with both their Hubble classification and color indices. However, for disk galaxies, standard concentration indices cannot be used to extrapolate with sufficient accuracy aperture photometrical measurements to obtain total magnitudes. Color distributions show that, even among early-type disk galaxies, there are examples of objects not exhibiting radial color gradients.
