Some bands are trying to work with fans on this. Blackmore's Night was very clear: first two songs, take pictures, take video, do what you do to your heart's content. AFTER song two (and Candace acknowledged that moment, so it was clear), you get caught taking pics/video, you leave the venue. Bruce, on Broadway, had a strict no phone/no video policy during the performance, but had a period - and it was a good five minutes, plus - where, after the last song, you could snap away, and he was cool about it. He would pose and he moved from side to side on the stage. He was clearly uncomfortable, but it was a concession to the fans (I think I noted this in my review; you can tell he's a star and he's become accustomed to his celebrity. He knows he's being photographed almost constantly, and he has a way of moving, "deliberately" is the best word, which allows for photos to be taken, without undue interference. I don't know what he's thinking, but it almost seems to me that he is giving them their moment, their "inch", and hoping they don't take their "mile" by crowding him or otherwise bullying him as paparazzi sometimes do.)
