Back by popular demand –  another opportunity to work with these incredible processes over 5 weeks

Gum Bichromate is a beautiful, early photographic technique originating from the latter half of the 19th Century.  A single negative is used, and it is a contact process using just one negative, which is exposed onto a sheet of paper. Several layers of watercolour, gum arabic and sensitizer are built up to realise a full tonal image. It is a slow, mesmerizing process, and is remarkably rich in subtle tones.

Cyanotype is also a contact printing process from the late 19th Century, but can also be used in conjunction with Gum Bichromate. The usual colour of Prussian blue of the cyanotype can be additionally enhanced with a duotone colour overlay with the gum Bichromate technique, giving the print an enhanced sense of space
