From a mere punter's viewpoint - much of this is a question of degree isn't it?

Not long ago a very well known British musician (you can guess who) made a return to gigging after several years of severe illness. His band's first gig, which I attended, was a triumph for him, the band, and the audience. Our man was absolutely bowled over by our genuine love and respect for him, and everybody went home very happy and uplifted. Many of the audience photographed the gig and the band's website duly got some free photos.

However - a few weeks later camcorders appeared and one vid went straight to YouTube without permission from the band. Now they are professional musicians and, strictly speaking, their intellectual property rights were being nicked.

A few weeks later, another very well known gent who was once in a band with the first gent appeared at the same venue. He specifically asked for no shots to be taken - and everybody respected that.

I videoed the second gent with his band at a festival somewhere around 1983 using a ginormous VHS camera and recorder. In those days you would only see one or two other people at a festival with video kit. I would never post the footage anywhere without his permission. But the genie's out of the bottle now - you can film an hour of good footage with something the size of a matchbox.

So I can only suggest that if musicians do not want stills or movies, they should make it clear at the outset and the audience should not be upset - after all doing gigs is some people's main source of income and they ain't gonna know where the pics/vids are going to end up.
