The collodion process is an early photographic process. The collodion process, primarily synonymous with the « collodion wet plate process », requires the photographic material to be coated, sensitized, exposed and developed in about 15 minutes, necessitating a portable darkroom for use in the field.

What is collodion used for?

What is the wet collodion process in photography?

The Wet-colodion process, also known as the collodion process, is an early photographic technique invented by the Englishman Frederick Scott Archer in 1851. This involves adding soluble iodide to a solution of collodion (nitrocellulose) and coating glass plates with the mixture.

What is a collodion mix?

collodion is Flammable syrup solution of nitrocellulose in ether and alcohol. There are two basic types: flexible and non-flexible. Flexible types are often used as surgical dressings or to hold dressings in place. When applied to the skin, collodion dries to form a flexible nitrocellulose film.
