Winter to Summer

A not entirely successful solargraph owing to the fact that the camera sagged for the first few days before I could get to refix it. Hence the gap between the lower suntrails and the upper ones.
A pinhole camera is set in place at the winter solstice with photographic paper in it for six months. It records the daily transit of the sun as it rises higher in the sky. The gaps in the trails are when it was cloudy, the lack of trails represent totally cloudy days.
You can just make out trees, buildings and vehicles too. I should have removed it on the 21st but what with one thing and another! I have just 'processed' it tonight.
