Abstract. Equivalent profiles of IC 783, IC 3328 and IC 3653, derived from HST and VLT images, are successfully decomposed using the classical two-component method of Kormendy (1977). Clearly distinguished are a bulge and a faint exponential disk, embedded in the spheroidal component. The blue-light profiles of IC 3328 and IC 3653 point to existence of a very bright compact nucleus.
