Troy Paiva, Urban Exploration and Night Photography
Urban exploration, by the way, refers to the examination of places that are usually off-limits to the rest of the world (we used to call it tresspassing when I was a kid, but now I know better because I'm more mature and more worldly). There has always been a big overlap between night photographers and urban explorers. Everyone has their own theories as to why that is. Wikipedia has a good introduction to urban exploration, along with links to more in-depth UE websites.
Thanks to Lance Keimig for finding this one.
