A positive image is a normal image. A negative image is a total inversion, in which light areas appear dark and vice versa. A negative color image is additionally color-reversed, [6] with red areas appearing cyan, greens appearing magenta, and blues appearing yellow, and vice versa.
The calotype process produced a translucent original negative image from which multiple positives could be made by simple contact printing. This gave it an important advantage over the daguerreotype process, which produced an opaque original positive that could be duplicated only by copying it with a camera.
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).
Black and white negative processing is the chemical means by which photographic film and 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.
Photographic papers fall into one of three sub-categories: Papers used for negative-positive processes. This includes all current black-and-white papers and chromogenic colour papers. Papers used for positive-positive processes in which the "film" is the same as the final image (e.g., the Polaroid process, Imago direct positive paper).
A single slide, showing a color transparency in a plastic frame Slide projector, showing the lens and a typical double slide carrier. In photography, reversal film or slide film is a type of photographic film that produces a positive image on a transparent base. [1]
The camera operator shoots a positive image and the film ends up as a negative. The original negative is printed onto stock that comes out as an interpositive. Often, two interpositives were made, one to be archived and one to continue through the process. The interpositive is color timed (to balance the scenes) into the internegative.
The edited original negative is then copied to create a safety positive which can be used as a backup to create a usable negative. At this point, an answer print will be created from the original camera negative, and upon its approval, interpositives (IPs) and internegatives (INs) are created, from which the release prints are made.
