Please Note - For the best chance of getting your photography-related question(s) answered, please consider posting it at the BCG forums. Not only do I check the forums first, but I seldom can get to all the photo-related questions I receive, so most go unanswered. Your best bet for a fast answer is the forums. 

Note that Steve is currently away (until Sept 1st) and not answering photography-related questions. Your best bet is to ask at the BCG Forums (linked above). Thank you.
