My brother-in-law's sister recently agreed to model for me, and we spent a very pleasant afternoon this past Saturday in her lovely home. I enlisted my own sister as assistant. Teresa has been working out body building so after doing some traditional portraiture, I had her pose with weights.
These are shot using mostly window light (big bay windows), aided by a 40" reflector (Photobasics 5-in-1 [a great deal, btw]).
