Wet plate photography workshop
Wet plate collodion process, a photography technique from the 19th century.
The ambrotype ( from Ancient Greek: ἀνβροτός — “immortal”, and τύπος — “impression” ) invented by James Ambrose Cutting in 1854, is a photograph that creates a positive image on a sheet of glass using the wet plate collodion process. (invented in 1851 in England by Frank Scott Archer.)
A black glass plate is coated with a collodion emulsion, then, it is sensitized to light by immersing the plate into a silver nitrate bath. The plate is loaded into the camera and exposure is made. Exposure takes about 2 to 30 seconds.
After being removed from the camera, the plate is developed in the darkroom by pouring a ferrous sulphate solution called developer. The remaining of silver particles untouched by light are removed and reveal the final image which is fixed by a secret recipe bath. After drying, the plate is coated with a warm varnish made of sandarac gum and lavender essential oil, used by Stradivarius for his violins.
The plate is ready for hundreds of years of archiving, ready to travel from descendants to descendants.
In this workshop, we will have an overview of the history of photography, a theoretical course on the chemistry involved for this technique, then we will do the shooting and the development of the ambrotype.
Each participant will create their own ambrotype to take home.
