I have a shoot Thursday that will present some challenges, photo of room below, and the final prints will be 40" wide. I have 250-300 people who will line the balcony, staircase and main floor. The area is about 80 feet wide and 25 feet high with mixed lighting. The snapshot below was taken at ISO 400, 1/100, f2.8 at 12mm. Because of circumstances the hotel wants me to use a minimum of gear. Although no specifics were mentioned I think more than two light stands and one tripod is on the verge of their definition of too much gear. And I'll only have 1/2 an hour to set up, get the photos and remove my gear. Any ideas?
