I had 90 minutes to create 13 portraits using a different background for each person, therefore, moving my lights for each person. I used two 580EX flashes on Pocket Wizard FlexTT5 remotes, firing them with a MiniTT1 with an ST-E2 on it so I could control lighting ratios right from the camera. The flashes were in Photoflex 24x30" softboxes.
