(Pocket-lint) - In 2012, Fine Art graduate Regina Valkenborgh setup a beer-can camera in order to capture a long exposure at Bayfordbury Observatory. The camera was set in place shortly after the London Olympics at the University of Hertfordshire's Observatory with the intention of capturing a long-exposure view from a static point. According to the University, Regina Valkenborgh had been interested in capturing imagery "without the use of modern technology" - and thus the idea to use a beer can lined with photographic paper as a simple pinhole camera was born. She placed the can at a spot by the Observatory then seemingly forgot about it until this year.
