Larry Sultan's The Valley (check out the photographer's statement (pdf)) is currently on display at SFMOMA.
I'm not quite sure what to make of this especially when I read descriptions like this one: "The Valley is by no means a documentary on porn filmmaking. Rather, it is a dense series of pictures of middle-class homes invaded by the porn industry. Sultan's lens focuses on pedestrian details [...] that offer clues to a bizarre other-world." Note the phrasing here: Homes are being "invaded" instead of rented out, and it's a "bizarre other-world". In a sense, it is somewhat of a bizarre world. On the other hand, billions of dollars are being made every year with pornography and a lot of that money is coming from the very same people who live in those middle-class homes.
