I built a wide angle pinhole camera with a shallow cardboard box, black spraypaint, duct tape, a pop can, and a pin. With it, I took a few pictures of nothing. This was taken at NDSU. Can you guess where? The most interesting thing about this image is that it is actually a paper to paper print of the original image. When you use a pinhole camera, you're actually exposing the image directly to the paper. This means that the paper will have a negative image on it. To get a positive image, you can lay the negatively exposed shot face down on a fresh sheet of photographic paper and shine a lot of light on it to expose it.
