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 an overpass, facing northeast. You can see, on the right side, the paths of the rising sun. While I placed my other cans vertically, with the flat ends up and down, this one was placed horizontally, and you can see the bizarre distortion at the top and bottom of the image. Unfortunately, some water got into the can, and caused the drops and streaks at the top middle. For my next batch, which will be ready to collect this summer, I added "eyebrows" over the pinholes to deflect some of the rainwater. 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.
