These images are made using Solarcans. These are aluminum cans similar to tall-boy beer cans. These cans, however, have a pinhole in the side and a 5"x7" piece of photo-sensitive paper (darkroom developing paper) inside.

To make an exposure, you first have to fasten the can to something stable. It should face the path of the Sun. Then remove a piece of tape that is over the pinhole. Often the can is left in place for several months. As the Sun moves through the sky it creates the curves on the paper, one curve per day. These images were started at the winter solstice and ended at the summer solstice. The nonlinear curve is formed because the earth is tilted on its axis.

These images were made near Kingman, Arizona. Thanks go to Ray and James Birkebile. They assisted in installing the first two cans, which were mounted on buildings in thei Birkebile compound. The third can was placed nearby in undeveloped property.
