A wonderful story HERE about a record breaking image that was accidentally created by someone doing a Fine Art degree at the University of Hertfordshire. Regina Valkenborgh was interested in capturing images without modern technology, so she created a pinhole camera from a beer can lined with photographic paper. She left the camera in one of the University's telescopes in 2012. Eight years later it was removed and the image was developed. The image is a superposition of 2,953 arcs, each of which is a record of the Sun's path in the sky. The University claims it is "...the longest exposure image ever taken".
