This magical activity is based on a photographic process: cyanotype. Using opaque patterns, you can create illustrated scenes on photosensitive paper. When exposed to sunlight, a negative of the patterns is produced on the paper. Then, all you need to do is rinse the paper in a clean water bath and watch as your creations appear on the blue background! A variety of elegant patterns to create poetic night pictures. Set inludes 8 sheets of photosensitive paper (21 x 28 cm), 4 composition pages, 127 patterns printed on acetate, 1 sheet of Plexiglas and step-by-step instruction booklet. A simplified activity with no need to mix chemicals! A whole new approach to illustration by printing patterns on acetate film! A magical, poetic activity where each creation is unique. An activity to repeat again and again thanks to paper refills for cyanotype (sold separately). Flower and plant patterns to enchance with real picked plants. Suitable from 7 years.
