I am aware of the photo explorers, a friend of mine is in management of the underground tunnels here in Toronto for the public utilities and he has a body of work that is very interesting, as well as the groups breaking into old castles and buildings, Detroit being a good example, but this one is very unique... I guess since its oversees and new to me I find it really amazing.
The first time I saw real good images of Angor Wat I was spell bound.. they were very large platinums by Kenro Izo back in the early 90's.
