Anthotype

An anthotype (from Greek άνθος anthos "flower" and τύπος týpos "imprint", also called Nature Printing) is an image created using photosensitive material from plants under the influence of light (e.g. UV light, rays of sun). An emulsion is made from crushed flower petals or any other light-sensitive plant, fruit or vegetable. A sheet of paper is covered with the emulsion, and then it is dried. Some leaves, a transparent photo positive or other material is placed on the paper; and then it is exposed to direct full sunlight until the image part not covered by the material is bleached out by the sun rays. The original color remains in the shadowed parts depending on the exposure. The paper remains sensitive against such rays. It cannot be fixed. Note: The color of anthocyanidins, anthocyans, carotinoids, and other light sensitive plant material may depend on PH of the water and of the paper.
