When I was photographing a theatre production recently, I had a quick conversation before the dress rehearsal, which went something like this: "Hi Robert, I'm the designer on this show - could you make sure you take some wide angle shots for my portfolio?"

Now, that's a perfectly normal, common and reasonable request - and one that raises an interesting question in terms of this sort of work: who exactly am I working for, or responsible to, when I photograph a show? And, how can I make them happy?
