Will you be in an auditorium of some sort? Do you have, or can you borrow an incident light meter, to measure the light falling from the over head lights? That will give you the BEST measurement. I agree, bracket! Will there be a 'dress rehearsal' that you can shoot, as practice?

I can try. bear, I have discussed lighting with the tech. The problem is that the lighting must be where the players can read the music. We don't use lights on the stands. Perhaps we should

It may not be to ones liking but the simple truth of the matter is that learning more about photography and gaining information is only one of many reasons people participate in forums like UHH. Some will place more importance on the social aspects of their participation because that’s what they lack. Some will post a question and not give a hoot about the response only that they were responded to, it’s a form of validation. I understand that this is not a forum designed or intended for personality issues but when you join any kind of public forum you must understand that all kinds of personalities will be there you just can’t let it frustrate you. It doesn’t take long to get to know which posters you enjoy and which you’d rather skip over.
