Originally, I was set on having an unplugged ceremony. Until I saw how many cute pictures come from guests. I'd also like some pictures to hold us over until we get sneak pictures from our photographer. Can anyone think of a cute/catchy/polite saying to put on a sign (like how you would with an unplugged ceremony) basically letting guests know that they are welcome to take photos, but they better not get in the way of the professional photos or have their phone visible in the pictures?
