Collodion is a pure type of pyroxylin used to embed specimens which will be examined under a microscope. While in Paris, René Dagron became familiar with the collodion wet plate and collodion-albumen dry plate processes which he would later adapt to his microfilm and Stanhope production techniques.

The translucency of paper posed an obstacle for relaying detail from negative to positive. This problem was solved in 1848 by the British sculptor-turned-photographer Frederick Scott Archer, who invented the wet collodion process, a means of producing negative images on glass plates.

Aug 16, 2024 · Flexible collodion is a cosmetic ingredient valued for its ability to form a protective and flexible film on the skin. Its effectiveness stems from its unique composition, which combines collodion with camphor and castor oil.

The collodion process, mostly synonymous with the "collodion wet plate process", requires the photographic material to be coated, sensitized, exposed, and developed within the span of about fifteen minutes, necessitating a portable darkroom for use in the field.
