Six months. That's right. This dream-like picture shows each phase of the sun over Bristol's Clifton Suspension Bridge taken during half a year.

The image was captured on a pin-hole camera made from an empty drinks can with a 0.25mm aperture and a single sheet of photographic paper.

Photographer Justin Quinnell strapped the camera to a telephone pole overlooking the Gorge, where it was left between December 19, 2007 and June 21, 2008 the Winter and Summer solstices. (That's a 15,552,000 second exposure.)
