Place any object or transparency on the Sunography Paper and leave to expose in bright sunlight. Rinse with water to reveal a rich blue print! Sunography paper or fabric contains light sensitive materials, which react to sunlight. Get creative! Use old photo negatives, x-rays, bits of lace, leaves, printed transparencies or even household objects to compose designs. Sunlight sensitive material (the cyanotype) was a forerunner of modern photographic processes. This type of print dates back to 1842 and was popularised by Anna Atkin, one of the first female photographers. // Pack contains 6 5x7" sheets // Made from 185gsm paper stock, printable on both sides. // Prints a 'prussian blue' colour when exposed. // Contains instructions // Suitable for ages 12 and up
