Will be photographing wedding Saturday.....I realize that I will be taking pics before and after wedding...reception etc.....but, what will I be able to take during the wedding? I mean how much moving around will I be able to do to take my pics? What should I expect and what will likely expect? Its not in a churh, so is it up to the B&G and what they want me to do? I don't know Im not really so sure that they do either.
