The picture below was taken using a home made pin hole camera over a six month period. The view is the Clifton suspension bridge in SW England. The camera was made by putting a single piece of photographic paper in a coke can with .25mm hole, taped to a telegraph pole. The lines are the tracks of the sun from the winter solstice to the summer solstice.
