You can find listings of photographers in your city's yellow pages, in local chamber of commerce listings and most importantly from personal references. Check with friends, business associates and family to see who they've hired for weddings. Once you have a few names, you should schedule an appointment to visit their studio. One of the most important things to consider in finding the right photographer for your wedding is to see their work. Ask for photographs of both day and night, and garden and church weddings.
Some photographers are better with natural light, others are better with articifical light.
Keep notes on what you notice. Also notice if the photographer's portfolio shows mostly formal shots or candid shots. Your personal taste in the type of photos you want for your wedding will help determine which photographer matches your vision and style. When reviewing a photographer's wedding packages, make sure they discusses the amount of time the photographer is available on the day of the wedding, how many rolls of film he'll take, whether or not you get copies of all pictures, the price of wedding albums, who keeps the negatives, and the cost of reprints. A reputable photographer should be able to outline these costs for you.
