CCD surface-photometry was obtained in order to determine the radial dependence of the surface brightness, ellipticity, and major-axis position-angle for 69 bright elliptical galxies in the Cousins V, R, I system. Using Fourier transforms, the deviations of the isophotes from pure ellipses were analyzed for systematic components. Systematic deviations larger than 0.2 percent in units of the semimajor axis were found for 80 percent of the galaxies, with the deviations generally appearing in the form of box-shaped or disk-shaped components.
