3 & 4 june 2017, at Mire, Nantes
During this workshop, we prepared two ancient iron emulsions mostly used in photography, Cyanotype and Van Dyke brown, that we coated on 16 mm films strips thanks to the addition of gelatine to the recipes. These emulsions are sensitive to UV light and are processed just by rinsing with water.
CYANOTYPE ( for about 100ml)
VAN DYKE BROWN
We coated the 16mm film strips (fixed BW raw print stock or fixed exposed BW stock) with the preparation usinf either brushes, sponges or the “madbox”. We tried the rayogramme technique with different items (plants, cloth, rice…)and “contact printing” putting exposed film strips emulsion side against the emulsioned film strip with a glass plate on it.
