[Padre]

I read about an idea, I tried it, and it has worked for me on various occasions. When you get ready to shoot, stop and turn around to the snappers and tell them they are now official wedding paparazzi. Tell them the rules are that they shoot when you call on them. So you take your shots and then turn and say, "paparazzi get your photos". They are usually amused and gladly enter into the agreement.
