It's always important to grab a shot of the dinner plates and tables before the ceremony starts...if possible. That's providing that there is enough time between you doing the couple shoot and when the venue lets the wedding guests into the Ballroom. For my wedding at the Laguna Beach Montage we made arrangements to make sure I was in there before the wedding guests were allowed to enter. This really made for such opportunity for photography....
