Definition. Emulsion refers to a mixture of two immiscible substances, such as oil and water, where one substance is dispersed in the other. In photography, emulsions are critical as they serve as the light-sensitive layer in film and photographic plates, allowing for the capture of images.
Photographic emulsion is a light-sensitive colloid used in film-based photography. Most commonly, in silver-gelatin photography, it consists of silver halide crystals dispersed in gelatin. The emulsion is usually coated onto a substrate of glass, films (of cellulose nitrate, cellulose acetate or polyester), paper, or fabric.
3 Νοε 2012 · In the first of a series of three posts, Colin Harding looks at the development of celluloid and how early photographers experimented with it. From the early 1850s, photographers had been looking for a practicable alternative to glass as a support for light-sensitised emulsions. The weight and bulk of glass plates added greatly to the ...
Evidence and theories suggest that the history of photography is not brief, but in the context of this treatise, a nevertheless brief history of photography is presented in an attempt to highlight the efforts of humans through the ages to understand and capture images permanently.
Art, History. Whereas the observation of numerous light-sensitive substances and the formative evolution of the camera obscura predate 1800, the invention of photography, as we know it, was essentially a 19th-century phenomenon.
