This is a 5-month exposure, showing the sun's path across the sky. I placed photographic enlargement paper, essentially low-sensitivity film, in a beer can with a pinhole. The homemade pinhole camera was mounted on a bridge, facing south. Being placed in a rather visible and accessible location, I was pleasantly surprised that my pinhole camera wasn't removed by a curious passerby or road maintenance employee. In fact, of the ten or so installed, only two went missing after 5 months.

Here are the instructions I followed to make the pinhole cameras.
