Contains twelve 4" x 4" sheets of sunprint paper and a Plexiglas overlay. This Plexiglas overlay helps press objects such as leaves flat in contact with the paper to insure a good print. Sunprints encourage an interest in the photographic process using only sun, water, and a bit of imagination. Place a fern, flower, or other object on the special paper and set it in the sun briefly. Then rinse the paper in water and watch as a beautiful long-lasting image appears.
