Multicolour photometry of pulsating stars in the Galactic Bulge fields

We present a study of photometric properties of very crowded stellar fields toward the Galactic Bulge. We performed a search for pulsating stars among thousands of variable stars from the OGLE-II survey supplementing the variability study with photometric measurements in four Johnson-Cousins UBVI _C passbands. Using these data, we analysed the properties of objects located at different distances and, whenever possible, classified them.
