YES I HATE IT!!!!!!!!!!!!!!!!!!!!!!! i will post up a picture and tell you why!!
I mean I got no problems with others bringing slrs (every single person has one these days anyways), but i hate it when they come in the way for the important shots (eg, the couple walking down the aisle, or when they put the wedding rings on etc). There has been plenty of shots ruined with others that come into the frame.
I will post up an example tonight when i get home.
But otherwise i got no problems at all. As long as you dont come into the way for the important shots I dont really care. hahah hope i havnt scared you, but take your camera man. Its good way to learn and to see what the pro's do and dont..
