I have photographed over 100 weddings...and disagree with many people...each one is incredibly wonderful! All of the weddings I have photographed have had unique details that represent the bride and groom.
My husband and I had a children's choir, made up of children that are significant to us. They sang a song written by a friend of mine, Merle Biggs durring the processional. Then, they lead the guests in singing "The Blessing" as my husband and we left the chapel.
