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.
An emulsion lift, or emulsion transfer, is a process used to remove the photographic emulsion from an instant print. The emulsion can then be transferred to another material, such as glass, wood or paper. [1] The emulsion lift technique can be performed on peel-apart film and Polaroid Originals integral film, but not on Fujifilm Instax film ...
Art photography print types refers to the process and paper of how the photograph is printed and developed. C-Print / Chromogenic Print : A C-Print is the traditional way of printing using negatives or slides, an enlarger, and photographic paper—through a process of exposure and emulsive chemical layers.
Photographic printing is the process of producing a final image on paper for viewing, using chemically sensitized paper. The paper is exposed to a photographic negative , a positive transparency (or slide ) , or a digital image file projected using an enlarger or digital exposure unit such as a LightJet or Minilab printer.
The print must then be rinsed in water to removed the fixer. The developer selectively reduces silver halide crystals in the emulsion to metallic silver, but only those having latent image centres created by action of light. [4] The light sensitive layer or emulsion consists of silver halide crystals in a gelatin base.
In some old processes, the film emulsion was hardened during the process, typically before the bleach. Such a hardening bath often used aldehydes, such as formaldehyde and glutaraldehyde. In modern processing, these hardening steps are unnecessary because the film emulsion is sufficiently hardened to withstand the processing chemicals.

Contact print of a photo film cut in pieces, used for reviewing and selecting images for the final print. Photo by Paolo Monti, 1975. Contact printing is a simple and inexpensive process. Its simplicity avails itself to those who may want to try darkroom processing without buying an enlarger.
