This magical activity is based on a photographic process: cyanotype. Using opaque patterns, you can create designs 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 the design appears on the blue background! These creations are then the night scenes forming backgrounds for the 4 poetic pictures and their illustrations. Set includes 4 laser-cut frames, 8 sheets of photosensitive paper (21 x 28 cm), 4 composition pages, 85 patterns printed on acetate, 1 sheet of Plexiglas, 1 sheet of double-sided stickers 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). Elegant laser-cut frames.
