Many photographers bring along samples of their work at different types of weddings. Look at their shots and ask yourself what types of work you like. Once you've narrowed down your choices, make arrangements to meet with potential photographers. Be sure to ask for references, and check with them to see if they were satisfied. Ask the photographers what their fees include.
Some photographers offer standard wedding packages that include a set number of portraits.
Find out whether you can order more pictures individually. Also ask whether the original wedding proofs are considered part of the package. It also pays to ask photographers how long they keep the negatives from the wedding. You might be strapped for cash now, but you'll probably want to order more prints in coming years. Once you've settled on a photographer, it's time to decide details like when to shoot the posed portraits on the wedding day.
