Two-color CCD photometry of dwarf galaxies in and around the M81, M101 and CVnI groups is presented. These observations are part of a long term project aimed at obtaining surface photometry data of all known dwarf galaxies within 10 Mpc. The global photometric parameters derived will serve as the basis for a comparison between dwarf galaxies in different galactic environments.
