Cyanotype & Van Dyke Brown Printing

Cyanotype printing and Van Dyke Brown printing are both contact printing processes, where a negative or an object is placed onto photosensitised paper or fabric, and exposed to the sun or a UV light. Photosensitive emulsion is brushed onto the paper by hand, making each print unique. This camera-less, iron-based technique was invented by John Herschel in 1842.

Cyanotype produces a Prussian cyan-blue print. Van Dyke Brown produces a deep brown print, similar to the popular paint pigment, Van Dyke Brown.
