Use this pack of five Sunography Colour Cards to get wonderful photographic prints using sunlight. Place any object on Sunography paper and expose in bright sunlight. Then, rinse in water and a rich blueprint will appear. Sunography uses 100% cotton archival watercolour paper that has been coated with a sunlight sensitive formula to produce images as sharp and detailed as a fine photographic print. Sunography is light sensitive on both sides so you can make two-sided prints. Sunography paper is a great platform for creativity. You can use old photo negatives, x-rays, bits of lace, leaves, household items or even transparencies from laser or inkjet prints to make images and collages and even add to a photo album. Dimensions: 3 x 5"
