Service Description

​​This workshop will be an introduction for complete beginners to single and double transfer colour carbon printing. Carbon photography is a 19th century continuous tone pigment transfer system with gelatine and coloured pigments as the main constituents. ​ The underlying principal in this process is that once the chemical, potassium bichromate*, has been applied to the surface of the gelatine to make it light sensitive, the gelatine becomes insoluble in proportion to the amount of light received, on exposure to ultra violet light. The exposed images can be transferred onto almost any prepared surface for development in hot water. The parts of the image that have not been exposed to UV dissolve in the water. The prints produced are archivally very stable and the tones rich and deep. ​ *Potassium Dichromate has now been replaced by a less toxic sensitizer called DAS. ​ There are a number of steps involved with preparation of materials, transfers of your print onto two temporary supports and then the final paper and drying times necessitate a five day workshop. ​ You will learn the history, production techniques and safe handling of chemistry for Carbon. You will be instructed in the preparation of coloured carbon tissues, sensitisation, exposure and the transfer of the exposed image to another substrate for development in hot water. Due to the nature of the materials used, humidity, constituents and light can effect the materials in unpredictable ways. You will learn to identify problems and how to resolve them. ​ Digital or hand drawn negatives can be used to produce a positive image. There is an A2 printer in the studio which can print negatives onto a roll of pictorico transparent film. You will learn to create the necessary photoshop curves as adjustments to your photographic image in preparation for printing with Carbon. ​ Digital Calibration: As we will be working with a package called CALIBRATION FOR ALTERNATIVE PHOTOGRAPHIC PROCESSES produced by The Wet Print, I would highly recommend purchasing this excellent and comprehensive online workshop in advance. The price is extremely reasonable at 59.95€. We will produce step tablets and calibration prints to measure with a spectrophotometer. I will guide you through the various steps. The workshop fee includes the cost of all materials, except imagesetter negatives. A limited number of workshops are available in the year, please email directly to make enquiries.
