We present optical surface photometry of four dwarf irregular galaxies in the M81 group: UGC4483, UGC5423, UGC6451, UGC6456. The data were collected at the Capilla Peak Observatory, New Mexico, with the RCA 512x320 CCD in March, 1993. We intend to combine the photometry observations with HI synthesis observations in an effort to better understand the dynamics of each galaxy.
