My 10-year old hamster lit with SB-5000 off-camera, 1/8 manual power. On-camera SB-300 operated as dumb optical trigger only @ 1/128 manual power. Key was bounced off 15" cardboard from a frozen pizza taped to a floor lamp. Ambient was fully suppressed, with fill and b/g being served by stray light from the key. The hamster received a $10 bribe for two shots.
