I don't know. I think that some of them are "locked into" particular poses and spend ages arranging them. I saw a programme recently on our national TV in which a wedding photographer (a woman) stated that people had to realise that some shots take up to 15 mins to pose. Did she ever ask the long-suffering bridal couple what they thought about this? I'm in demand (by people who know me, I only do it for them) partly because I'm fast. I don't think you should hog the wedding!
