ABOUT PLATINIUM/PALLADIUM PRINTING AND GUM BICHROMATE: Printing in platinum and palladium is acknowledged as the summit of alternative processes – images formed in totally permanent ‘noble’ metal. Gum bichromate printing over palladium or platinum photographs is an effective method of using colour to built depth to enrich shadow areas. The (more…)
ABOUT THE KALLITYPE PRINT: Although often confused with Van Dyke Brown and Argerotypes it is more related to platinum and palladium printing in its evolution and tonal values. Due to this it was known as “the poor man’s platinum print”, when the image is toned in platinum or palladium the result is chemically close to (more…)

ABOUT THE ARGYROTYPE PRINT: This ‘user-friendly’ iron-based silver printing process was devised in 1996 by Mike Ware, using an unusual salt – silver sulphamate in a ‘single-bottle’ sensitiser solution with a long shelf-life. The resulting purplish-brown print of nanoparticle silver has a finer gradation than the traditional iron-silver processes, (more…)
Four Colour Carbon ABOUT THE CARBON PROCESS The carbon process, initially a black-and-white process using lampblack (carbon black), was invented by Alphonse Poitevin in 1855. The process was later adapted to color, through the use of pigments, by Louis Arthur Ducos du Hauron in 1868. Carbon photographs were the (more…)
ABOUT GUM BICHROMATE Gum Bichromate process allows colour printing from black & white contact negatives in numerous colours. Paper is coated with pigment, dichromate and gum Arabic, registered, exposed to ultraviolet light. Exposure to light hardens the gum Arabic proportionate to the varying density of the negative.The print is then placed in a bath of (more…)
SALT & ALBUMEN PRINTING: the two processes are closely aliened not only in the history of photography but in the practice of creating these two most beautiful processes. ABOUT THE SALT PRINT: This is a simple process with a number of challenges to master. Salt prints are created by coating paper in a solution of (more…)
ABOUT CARBON PRINTING The carbon printing process uses colour pigments producing one of the the most permanent coloured photographs. The use of pigment allows any colour photograph on almost any surface. The beautiful tonal scale resolves fine detail. It relies upon the (more…)
PRINTING PHOTOGRAPHS ON FABRIC The workshop allows you to create photographs on natural fibres, cotton, linen and silk with a surprising clarity. It provides the following advantages over paper: Movement – especially silks Can be stretched onto a frame Wearable – cyanotype can (more…)
ABOUT CYANOTYPE This process requires no other chemicals, can be exposited in sunlight and developed simply in water. Cyanotypes provide a beautiful image in stable Prussian blue pigment. The image colour may be easily modified by a variety of toning agents. THE CANOTYPE HISTORY Sir John Herschel’s Classic/traditional cyanotype process, now practiced for 166 years, (more…)
