Constructing a Pinhole Camera
Our NIST Adventures in Science class made pinhole cameras out of recycled aluminum cans collected in Rock Creek Park. Instead of photographic paper, we used sunlight sensitive paper to record our images of the migrating sun. This meant we did not need a dark room to insert the paper in the aluminum can. A three week experiment of the camera's tracking of the sun across the winter sky yielded the image below (left) that was then scanned and converted to a positive image on the right with simple photo manipulation software.(Ideally, a pinhole camera tracking the sun should be left in place to view the sun's path across the sky for several months.
