This historical photographic process, which can only be used to capture still forms, was invented in the mid-19th century. It involves the coating and sensitising of the photographic material, which is then exposed and developed over a short period of time. From the late 1850s to the 1880s it was the dominant medium for portrait photographer, replacing the daguerreotype; it in turn was supplanted by gelatine dry plate.
Wozniak's workshop is available for three students on two separate days. It takes place at Peacock Yard in Walworth, south London. Open to those with no prior experience, it will both teach participants about the technique and allow them to create their own images on 4.7’ x 6.5’ glass and aluminium plates.
