As a general rule I don't photograph weddings but I assisted at one at the weekend and was able to capture lots of moments that the main photographer wouldn't have been able to shoot on his own.  The ceremony was in Greenwich at Charlton House, which is supposedly haunted by several ghosts but none of them made an appearance (as far as I could see).  The brief was for mainly reportage, with all the formal group shots coordinated by the ushers, although I did manage to include one person who wasn't on the list.
