Fifth Day of Christmas-Solargraphs

Jan Koeman of the Netherlands takes half a year long pinhole photographs with beer cans. He describes his process:

Catching the Sun in an empty beercan. This is how a photo with an exposuretime of nearly 6 months looks like. Tonight is the Winter Solstice, so I had to remove the photographic paper from my empty beercans that I used as a pinhole camera to catch the sunlight. This is called a Solargraph.
