The brother of the bride doesn't want his picture taken. He made loud and relatively aggressive statements about it. OK. You don't want your picture taken. But your sister is getting married to one of my very good friends. You WILL be in some photos. Or you could just put a bag over your head... Fercryingoutloud! You are sitting next to the bride. Are you completely self-centered? As it happens, I think so.
The funny part? One of his nieces said in passing, "Just use a telephoto." Her dad is also a shutterbug with a Nikon D300. And a faster telephoto lens than I've got. Odds are, there are more photos of this man than he knows.
