We present BVI CCD photometry of a sample of 11 elliptical galaxies chosen to cover a significant range in absolute luminosity. Our observations of the larger systems include exposures taken with the galaxy off-centre, allowing a better estimate of the true sky-background. We have used model-fitting to measure the structural parameters (ellipticity, position angle of the major axis, and the Fourier 4θ terms) of these systems, as well as determining the (B - V) and (V - I) colours as a function of radius. In contradiction to some previous observations, we find that none of the galaxies has significant, large- scale radial colour gradients. Three galaxies have shells or arcs - structure not previously detected in either NGC 3091 or NGC 4936.
