Photographed in a vacant prison late at night. Amazingly these colours are real and how the RAW file came off of the camera. However, I could not see these colours when I was there in person, there were a series of tiny coloured bulbs built into panels and alarm systems along the length of the wing. Across the length of a 2 minute exposure these tiny coloured bulbs spread their glow and created the much larger pools of light you can see in the end result. One of the reasons I love long exposures.
The image forms part of the multi award-winning Forgotten Heritage photography project, which has been running since early 2012 and features imagery from lesser known historic, abandoned and hidden locations throughout Europe.
