I know it's been a while this thread has been posted on. I don't really photograph weddings fully. I've assisted/second shot a few, I photographed a reception for some friends (ceremony was off limits due to it being held in Mormon temple), and I have a couple of upcoming weddings for friends. I read this thread all the way through purely for something to do on this boring day. Haha! Anyhow. One thing I didn't see mentioned, which I thought would be a good tip. At a couple of the weddings I assisted at, we had a mention of a family member that needed to either be separated from another (i.e. Ex husband/wife) and could not be in the same photos together. As well at one, we got word last minute that the groom's father had opted out of any formal photos. So when going through the list of formal photos of family members, not to call his name for photos. So I guess the tip would be to check with the B&G if any family members cannot be in photos together due, that way to avoid any drama that may arise during formal photos.
