Using HST archive observations for three disk galaxies at redshifts z = 0.15, 0.90 and 0.99, and the astronomical data processing system IRAF/STSDAS, we derived their surface brightness profiles. Derived luminosity distributions were reduced to standard V and I magnitudes. After corrections for cosmological distortion (k-correction), the surface brightness profiles in a galactic rest-frame B color were obtained. Using a two-component (bulge plus disk) approximation, parameters for the bulge and the disk components were calculated. We noted that for all the three galaxies the best-fit models for the disk decrease with radius faster than exponentially.
