Floral Calder Cyanotype Card RF12

Product description

Botanical unique cards created from pressed flowers and plants from the artists garden and around Calderdale, using the Sun.

The cyanotype process is a camera-less photographic technique creating a Prussian blue image by exposing a light-sensitive coated paer to UV light (sunshine). These beautiful cards are giclee prints from original works.

This photogram technique was invented in 1842 by Sir John F. W. Herschel and originally used for reproducing maths tables, documents and technical drawings, known as blueprints, as well as for documenting and cataloguing botanical species, notably by early adopet Anna Atkins.
