ABOUT THE WET PLATE PROCESS: Tintypes, Ambrotype and wet plate glass negatives.
A plate is coated with collodion emulsion and sensitized, exposed in a large format camera and processed in the darkroom. The name wet plate is used as the solution must remain wet during the whole process. It loses its sensitivity to light when it is dry. The activity of preparing a plate of glass with salted collodion and silver nitrate, exposing the plate, and developing the image takes place within ten minutes.
THE WET PLATE NEGATIVE HISTORY
The collodion process was discovered by Englishman Frederick Scott Archer in 1848, he published the process 1851 and by 1860 was universally employed by photographers until 1880 when the gelatin dry plates became widely used. Collodion glass-plate negatives became the standard for photographers. This coinciding with the first three decades of albuminized paper and the combination of the two became the rule. The focus of this negative was simply on the final photographic product: the positive print.
ABOUT THE WORKSHOP:
The day includes TINTYPE, AMBROTYPES and GLASS PLATE NEGATIVES – It involves understanding the preparation of the plate for each of the processes, coating, exposing and processing. The chemicals used are volatile so this workshop is not for those who have concerns about handling these types of chemicals. Material handling safety issues are included as part of the workshop. The Tintypes and ambrotype are final positive images. The focus of glass plate negatives is simply on the final photographic product: the positive print.
ABOUT ELLIE YOUNG:
Since 1994 Ellie has been practicing and studying the art craft and science, of ‘alternative’ photographic processes. Ellie conducts workshops in a number of alternative processes in her studios, and at times also teaches these processes in collages and institutes around Australia. Ellie constantly exhibits and sells her work nationally and internationally.
