This is an old one from an abandoned borstal in Leeds. Kids had broken in and burnt a lot of it down, hence the fire damage. It was like something from a horror-themed computer game.
This is a "fake" HDR created from a single raw file. It was pitch black in there, with the only light coming from my flash.
Shot on a canon 400D with a Tokina 10-18mm fisheye and bounced Canon 430EX flash.
