In this work we presented the results of our study of photometric variability of cataclysmic variables V795 Her and GK Per. These results were obtained in frame of extended observational program that is carried out in Sternberg Astronomical Institute during the last years. The numerous broad-band UBV and CCD observations of these variables were obtained on the two 60-cm telescopes in Crimea. The light curves of both stars were determined by our observations and analyzed. CCD observations of GK Per carried out in V band during the outburst in autumn of 2004 outburst distinctly show the existence of variability with the period of about 80 min. Our analysis based on the observations of V795 Her with 10 sec resolution revealed variability with the period slightly different from the orbital period.
