i second all that. traditional, lifestyle, photojournalistic, photosureal, artisitc, documentary, commercial, whatever kind of photography they claim to be or not to be just look at photos from an entire wedding and make sure you like the photos through the entire day from begining to end. you can give the camera to a monkey and they can get some great shots to put up on a website but that wont give you a true understanding of the photographic style of the monkey. you might see a photographer who has a very photojournalistic shot up on their site when really they are very traditional and posed through the entire thing.
id say all in all most photographers these days (especially on this site) are very photojournalistic/lifestyle and thats what most people are looking for. they want their entire day documented and not just a couple shots at the ceremony and reception like my parents wedding (sorry to my mom and dads photographer hahah)
