The quality of the photometry parameters derived from VLT images for cluster (left) and field (right) galaxies. Histograms of the differences between structural parameters derived from bulge plus disk GIM2D fits to the HST ACS and VLT I band images of the isolated, undisturbed galaxies with measured velocity dispersions. The mean, rms, and the widths at the 68% percentile of the distributions are given.
