There are a lot of wedding photographers out there so how do you pick one that's right for you? Who is the best wedding photographer....for you.
Everyone has their own style of photography and photos they do and don't like. Some like candid documentary shots and others like more traditional. There is no right or wrong style, it's what do YOU like and what is YOUR style.
Once you know this try to find examples of wedding photography that matches this style with a photographer. You'll see common threads in photographers portfolio that will answer this for you.
Then you need to meet them. Their personality is just as important as their photos. You will need to feel comfortable with them so that you can relax and be yourself. They should feel like a friend so that you almost don't notice them when they are taking your photo.
Then when all this fits together you need to hope they have your date free!!
