Color positive picture (A) and negative (B), monochrome positive picture (C) and negative (D) In photography, a negative is an image, usually on a strip or sheet of transparent plastic film, in which the lightest areas of the photographed subject appear darkest and the darkest areas appear lightest.

Technicolor introduced Monopack, a single-strip color reversal film (a 35 mm lower-contrast version of Kodachrome) in 1941 for use on location where the bulky three-strip camera was impractical, but the higher grain of the image made it unsuitable for studio work. Eastman Kodak introduced its first 35 mm color motion picture negative film in 1950.
Kodacolor is a color negative film that was manufactured by Eastman Kodak between 1942 [4] and 1963. It was the first color negative film that they marketed. When introduced, Kodacolor was sold with the cost of processing the film included, but prints were ordered separately. Both the film and processing procedures were revised through the years.
Unlike some color reversal processes (such as Kodachrome K-14) that produce positive transparencies, E-6 processing can be performed by individual users with the same equipment that is used for processing black and white negative film or C-41 color negative film. The process is highly sensitive to temperature variations: a heated water bath is ...
Negative: light will toughen the resist and create an etch resistant mask. To explain this in graphical form you may have a graph on Log exposure energy versus fraction of resist thickness remaining. The positive resist will be completely removed at the final exposure energy and the negative resist will be completely hardened and insoluble by ...
A chromogenic print, also known as a C-print or C-type print, [1] a silver halide print, [2] or a dye coupler print, [3] is a photographic print made from a color negative, transparency or digital image, and developed using a chromogenic process. [4]
C-41 is a chromogenic color print film developing process introduced by Kodak in 1972, [1] superseding the C-22 process.C-41, also known as CN-16 by Fuji, CNK-4 by Konica, and AP-70 by AGFA, is the most popular film process in use, with most, if not all photofinishing labs devoting at least one machine to this development process.
The process of constraining the available colors to a specific color palette effectively throws away a certain amount of color information. A number of factors can affect the resulting quality of a color-reduced image. Perhaps most significant is the color palette that will be used in the reduced image.
