Justin Quinnell must have the patience of a Saint. He assembled & installed a number of handmade pinhole cameras around Bristol, leaving them untouched for 6 months, yes, 6 months. His project was to record views of Bristol, UK, with the sun trailing across the sky during the Winter Solstice (December 22nd) thru the Summer Solstice (June 2oth).
To better understand the picture below (Clifton Suspension Bridge. Bristol, UK. Dec 17, 2007-June 21, 2008), the wavy light streaks seen are that of the sun...the lowest streak shows the suns path of the Winter Solstice, while the highest streak shows the suns path of the Summer Solstice.
