I love focusing on hands during the wedding day. They say so much about what is really going on inside a person or between a couple. Too many times, a face can fake a smile or a loving feeling- but the hands never lie.
Some of my most dramatic shots have been from photographing the hands of a couple during the first dance, the fingers of the groom as he awaits his bride at the altar, the father of the bride as he holds his daughter for the last time.
I always tell my second shooters to respect the hands.
