Can I bring a camera?

Cameras are ok if not professional or have attachable lenses.

It depends on the show

Yes not a professional one and i think the lens has to be less than 6 inches

Yes

Cell phone cameras are okay. Not sure if you can do a professional shoot without permission.

Cameras are allowed as long as they're not professional.

I'd give em a call.

Depends on the artist

Dending on the event it may he allowed. Dont know officially though.
