A party photographer. This artist documents people, usually young privileged white kids, and their wild lifestyles. Classic photographers who fit this category are Larry Clark, director of KIDS. A contemporary artist would be the Cobrasnake.
The preferred format for this type of photography is digital, while polaroid appeals to a more specific/pretentious genre of wild lifers. Also, the portfolio's of wild-life photographers are usually their facebook pages.
Me: My friend Kara is an avid wild-life photographer
You: Oh, I didn't know she photographed animals
Me: She's doesn't photograph animals, she photographs PARTY ANIMALS!
