The ultimate challenge - a last minute group photo of ~300 people with no advance access to the space. We set up lights in the hall based on a plan to 'bounce' the strobes off the ceiling. The ballroom was set up with people sitting at tables; we had a team of three people, five studio lights, and a 15 minute window in the schedule to get people out of the ballroom, strike the tables, move/set up lights, test lights, get people back in, pose them, and capture the group. Done in 13 minutes!
