I once saw a documentary called "Dead Places" while attending a film festival back in high school. It contained videos of the insides and outsides of abandoned buildings. I found it fascinating.
This guy, Seph Lawless, whom I've been following for a while now also captures the state of old abandoned buildings, but also happens to be a stellar photographer. He doesn't limit himself to just building however, but might include abandoned theme parks, airports, racetracks, etc.. I'm excited for him to publish this upcoming book.
