I'm shooting Tmax 400 in Rolleiflexes. I just got a Sunpak 555. I want to document my little guy (10 months old, crawling, on the verge of walking) in my home. He's in constant motion so focusing is a challenge. Ideally I'd like to be shooting at f/11 which is the appropriate aperature when the Sunpak is set to Auto. The problem is I don't like the dark background - the "Crime Scene Photo" look. When I pivot the flash head to bounce off the walls or ceiling my working aperature drops to f/4 - not good for DOF and tracking the little guy. Next I'm going to try using my SB-800 as an optical slave remote w/diffuser to light up the background. Any other tips, ideas?
