I was lucky enough to be born with a former professional photographer in my immediate family. Otherwise, I wouldn't have known what to expect or ask for from my wedding photographer. If you are not in a similar situation and want to be sure to get the pictures that your special day deserves, I've found an article that can help.
Why don't couples spend time getting to know their photographer? Yes, they specialize in wedding photography but every wedding is different. You might have a specific list of shots that are important to you and unless you communicate this to your photographer, he/she might not capture those special moments.
