There are three types of photographers: photojournalists, traditional wedding photographers, and those with a balanced bag of tricks. Ask yourself: Do I love candid black-and-white action shots? If you answered yes, then you are leaning toward a cameraman with a photojournalism style. Perhaps, you prefer portraits and posed shots. If you do, then a traditionalist is for you. Ambivalent? Can't decide? Then seek out that photographer with a special mix of talents.
This is not a decision that can be made on looks alone you must meet your potential photographers in person. If you like what you see on their sites and their fees are in your ballpark range. Call to see if they're available for your wedding date. If the photographer is already booked on your date, you may want to see if they have an associate or can recommend another shooter with a similar style. Set up in-person meetings with three to five potential photographers who are available on your wedding date to look at more of their work and assess whether your personalities mesh. Be prepared to talk about your venue, your wedding style and what you envision for your photos.
