Printing paper mainly with silver bromide emulsion.
A graph used to show a film emulsion or developer's limits of tonal reproduction, relative speed and fog level.
A warm-tone printing paper that has silver chloride and silver bromide emulsion.
The time taken for a film emulsion to lose its milky appearance at the fixing stage of film processing.
Irregular marks on a film emulsion caused by uneven drying when processed. This can be prevented by using wetting agent in the final wash.
A process where the slither-like image-carrying surface of a Polaroid print is removed from its base and repositioned on a new paper or film support.
Natural protein, derived from animals, that's used to suspend silver halides evenly in an emulsion form on the paper and film's surface.
Chemical used at the fixing stage to toughen the film's emulsion and make it more resistant to scratches.
The Foveon X3 direct image sensor is a new technology that works like film. Foveon pioneered the development of the direct image sensor using advanced developments in semiconductor design, image processing, and signal processing. Their X3 sensor directly captures red, green, and blue light at each point in an image during a single exposure. Similar to the emulsion layers used in colour film, Foveon X3 image sensors have three layers of pixels. The layers of pixels are embedded in silicon to take advantage of the fact that red, green, and blue light penetrate silicon to different depths - forming the first and only image sensor that captures full colour at every point in the captured image.
