Justin Quinnell makes very long exposure photographs using a pinhole camera.

One of Justin Quinnell’s long-exposure photographs, from his pinhole photography site.

This one shows the tracks of the sun over the Clifton Suspension Bridge, Bristol, UK during a six-month exposure from 19 December 2007 to 21 June 2008.

Apparently the pinhole camera was made from an empty drinks can with a 0.25mm aperture, strapped to a telephone pole overlooking the Gorge.

Dotted lines of light are the result of overcast days when the sun was less consistently visible.
