Positive film, which is used to develop photos (slides) that would go into a slide projector, is also known as “reversal,” “slide,” or “transparency” film. It is a film or paper record of a scene that represents the color and luminance of objects in that scene with the same colors and luminance (as near as the medium will allow).
In photography, reversal film or slide film is a type of photographic film that produces a positive image on a transparent base. [1] Instead of negatives and prints , reversal film is processed to produce transparencies or diapositives (abbreviated as "diafilm" or "dia" in some languages like German , Romanian or Hungarian ).
Photographic processing or photographic development is the chemical means by which photographic film or paper is treated after photographic exposure to produce a negative or positive image. Photographic processing transforms the latent image into a visible image, makes this permanent and renders it insensitive to light.
An interpositive, intermediate positive, IP or master positive is an orange-based [clarification needed] motion picture film with a positive image made from the edited camera negative. The orange base provides special color characteristics that allow more accurate color reproduction than if the IP had a clear base like an exhibition positive. [1]
Photographic prints can be produced from reversal film transparencies, but positive-to-positive print materials for doing this directly (e.g. Ektachrome paper, Cibachrome/Ilfochrome) have all been discontinued, so it now requires the use of an internegative to convert the positive transparency image into a negative transparency, which is then ...
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 ...
In the traditional photochemical post-production workflow, release prints are usually copies, made using a high-speed continuous contact optical printer, [5] of an internegative (sometimes referred to as a 'dupe negative'), which in turn is a copy of an interpositive (these were sometimes referred to as 'lavender prints' in the past, due to the slightly colored base of the otherwise black-and ...
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.
