Extreme Photography: Six Month Long Exposure

British pho­tog­ra­pher Justin Quin­nell is mak­ing waves with an amaz­ing six month expo­sure he made in Bris­tol, Eng­land of the sun ris­ing and falling over the city’s famous sus­pen­sion bridge.

He made the photo not with a fancy dig­i­tal cam­era but with an extremely rude, home­made device — a pin­hole cam­era made from an empty soda can with a .25mm hole punched in it and one sheet of photo paper inside. He strapped it to a tele­phone pole and left it there for six months, from Decem­ber 19, 2007 to June 21, 2008. If those dates sound famil­iar (or astro­nom­i­cally sig­nif­i­cant), they are — they’re the win­ter and sum­mer sol­stices, respectively.

The low­est arc in the photo is the sun’s trail on the short­est day of the year, the win­ter sol­stice. The high­est arc is the sum­mer sol­stice. The lines which are punc­tu­ated by dots rep­re­sent over­cast days when the sun pen­e­trated the clouds only intermittently.
