The main photometric parameters of six very low surface brightness dwarf galaxies of the M81 group are obtained. For the first time the luminosity profiles of extreme dwarfs outside the local group are given. The profiles are much more consistent to the exponential law than to the r 1/4 law. No significant differences in profile between irregulars and sphericals could be found.
