Not to be missed! A very special opportunity to work with these incredible processes.
Gum Bichromate is a beautiful, early photographic technique originating from the latter half of the 19c. 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 19c , 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
