Our paper produces beautiful, permanent prints from natural or man-made materials. This unique sun-sensitive paper exposes in direct sunlight to create white on blue prints. Flat objects such as leaves, photo negatives, coins, cut-outs, lace, etc., when placed on the paper block the sun and provide the subject for the print. This photographic-like image requires no inks, presses, photo equipment, darkroom, or chemicals. Exposure time is 2-3 minutes, then develop in tapwater in seconds. It's fast, safe and leaves no mess. NaturePrint™ Paper is appropriate for any age group and includes full, simple instructions.
