It totally depends on the event. It isn't the venue prohibiting that. In most cases it's the artist you're seeing. They've definitely lightened up about it because everyone is taking pictures with their phones anyway. Best to contact the promoter to know for sure.
Unlikely. They will do full searches. But not 100% sure. Read venue FAQ's.
No "big" or professional cameras.
They don't allow professional cameras and no flash
Depends on the performer/artist(s) for each show. Check website for details. Should be included in the fine print prior to purchasing tix.
No not usually. They usually only allow small cameras and phones.
Nope
Up to artist, not venue. This was told to me by event security at the QOTSA concert back in January.
