Visit a few websites and choose a few to call and go meet.  Just emailing is not enough to be sure you can get along with the photographer.  If you don't like the photographer you will not look good in the photos, period.  Also beware of a large studio that "hand picks" the photographer for you.  Don't fall for their high pressure salesman, you absolutely must meet the photographer you will work with before signing the contract.  Make sure the photographer's name is on the contract.

Do you absolutely love their best photos? Make sure to ask to see more than just their "best", ask to see 2-3 weddings of ALL the proofs that are within the last year.
