Observations of 39 nearby, mostly dwarf galaxies are presented.
The observations were carried out at the 1.2-m telescope of
Observatoire de Haute-Provence (France) with 
and I
Cousins filters. Based on surface and integrated photometry
of the obtained images we derived total and I magnitudes
and integrated 
, 
colours as well as radii and magnitudes
at the 25m isophotal level.
Azimuthally averaged surface brightness profiles were derived
for 33 galaxies in each photometric band. Most of the profiles
can be well fitted by an exponential intensity law of brightness
distribution. The best-fitting exponential parameters are also
given for the galaxies.
Key words: galaxies: fundamental parameters / galaxies: photometry / galaxies: irregular / galaxies: structure
