Developed by educators at UC Berkeley’s Lawrence Hall of Science, Sunprints encourage an interest in the photographic process using only sun and water. Place a leaf, flower, or other object on the special photosensitive paper and set it in the sun briefly. Then rinse the paper in water and watch as a beautiful long-lasting image appears. Use your creativity and see what develops. Kit includes twelve 4” x 4” sheets and 1 acrylic overlay. Refill pack includes twelve 4" x 4" sheets.
