Multi-band SBF studies are a unique and quite promising way of constraining stellar population properties, especially when combined with additional information. SBF data could help enormously in understanding TP-AGB evolution and hot stellar components in elliptical galaxies. Although there has been much theoretical modeling in this regard, the observational studies to date have been limited. The current lack of an efficient large-format space-based camera is a big blow, but currently available large-format near-IR imagers and the coming generation of multi-band digital sky surveys provide interesting prospects for new SBF studies. We have only scratched the surface of this field.
I wish to thank the conference organizers for inviting me to talk on this subject. I am indebted to my collaborators on the ACS Virgo and Fornax cluster surveys for their many contributions to this work, my colleagues at Teramo Observatory for their hospitality following the conference, and Hyun-chul Lee for providing figures prior to publication.
