I think you guys are right. As much as I'd like to use the gray, it will have to wait for another time. My only lighting change for this set is going to be barn doors for the background light. I'm hoping to be able to move the light around a little and not get spill on the model.
For Cathryn's session I used the AB-800 main, SB-800 fill, and AB-1600 for the background. Octobox main, white umbrella fill, and silver umbrella for the background. I usually keep my white foamcore bookend opposite the main for some low fill.
For you lighting nuts like me, I picked up what I think is a great book on portrait and lighting. It's called "Photographing People: Portraits - Fashion - Glamour" by Roger Hicks and Frances Schultz. Great portraits and excellent lighting descriptions. A hardback for under $16 at Amazon.com.
