Those individual lines are images of the sun trailing across the sky: The lowest one is the winter solstice, captured on December 22nd, and the highest one is the summer solstice, which took place on June 20th. Quinnell, a professional pinhole photographer (he consulted and shot The Brothers Bloom as well) has done this kind of very long-term exposure before, including another six-month shot of his hometown of Bristol, but it's not the easiest project to undertake:

Most of the cameras survived 6 months of wind, rain, hail (and being thrown in the bin!). Several were blank; one was full of water, (the emulsion on the photographic material having floated off.) and one, still exposing, currently sits inaccessibly under 10 foot of bramble, waiting forever to be recovered.

It's pretty amazing stuff. There's nothing like a six-month-long exposure to make your camera's panoramic mode seem like child's play. [Pinhole Photography]

So I guess we're not going to need a bigger boat after all. [via DailyMail and Getty Images]
