"Ferric Gum" Workshop *NEW*

Centre Cívic Pati Llimona, el Barri Gòtic, Ciutat Vella
Teacher: Emily Kirkpatrick. The ferric-gum process, invented in the 1970s, is a modern and less toxic adaptation of gum bichromate, a technique from the early years of photography. During the workshop students will learn to coat the paper, expose the image, apply the gum and pigment, and develop the final image.
