This has probably been done to death here, so I apologise, but ....
The venue I'm going to tomorrow night has this on their web site:
"No professional 'type' camaras [Sic], video camaras [Sic] or tape recorders will be allowed in the venue."
So I may get harassed by the security people because I've got an SLR, but everyone else with a mobile phone will go in without a problem. Next morning, they'll have posted their videos on Youtube, with dreadful sound and image quality, and do the artist a big disservice.
Meanwhile, I'm just a fan, who's bought some gear with which to try to do the job properly. I'm not trying to make anything out of taking photos, just trying to take good shots of an artist I respect.
Last week, family members of this same artist asked me for some of the images I'd taken and posted on the web, so I can't be doing too much harm - or can I?
It's a mad world, isn't it? Anyone had similar problems, with advice on how to slide past the restrictions?
