ABOUT GUM BICHROMATE
Gum Bichromate process allows colour printing from black & white contact negatives in numerous colours. There is a high degree of artistic control in this beautiful print making process. Paper is coated with pigment, dichromate and gum Arabic, registered, exposed to ultraviolet light. Exposure to light hardens the gelatin proportionate to the varying density of the negative.The print is then placed in a bath of water to allow the soluble gum, excess dichromate, and pigment to wash away.Colour layers are built up by repeating the coatings with careful registration
HISTORY OF GUM BICHROMATE
In 1839 Mungo Ponton discovered light sensitivity of dichromates. William Henry Fox Talbot later found that colloids such as gelatin and gum Arabic became insoluble in water after exposure to light. In 1858, John Pouncy used colored pigment with gum Arabic to create the first color images.
ABOUT THE WORKSHOP:
There is a high degree of artist control in this beautiful print making process.
During the workshop you will create a number of images. The following issues and many others will be covered:
- CMYK negatives for control of colour and contrast
- Alignment or registration of negatives
- Ways of coating the paper
- Different colour pigments that can be used
- How to build up and control colour during processing
ABOUT ELLIE YOUNG:
In 2000 Ellie attained the National Gallery of Victoria Trustee Award 2000 for her work in Gum Bichromate printing. Since 1994 she has been practicing and studying the art craft and science, of ‘alternative’ photographic processes. Ellie conducts workshops in a number of alternative processes mainly in her studios, but also teaches these processes in collages and institutes around Australia. After some years of research, her Salt Printing Manual is due to be released in 2010. She constantly exhibits selling her work nationally and internationally.
