Of course I don’t mind your guests photographing excessively on your very special wedding day. However, I don’t like guest photographers jumping in front of me during an important shot LOL! As in this day and age, it’s not very possible to control.
However, as the official photographer contracted to produce my best work for you; I will let the bride and groom know if a guest does make it difficult for me… Normally I politely, but assertively say to your guests that have cameras in hand that I would like to always shoot first and then they can fire away immediately afterwards.
