A few years back, I finagled 2 press passes for the MCM Comics Expo, which is also one of the bigger cosplay events in London. I was using a fairly portable lighting kit anyway, but the press pass made everything much smoother. I found an unused booth section with an unobtrusive backdrop, then set up one light stand while my assistant grabbed people to shoot. She held the other light up for me. Strobist info: two lights in a cross light setup, plus the ambient. One shoot-through umbrella as the main light, plus a bare speedlight (I think), goboed for the cross light.
