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.

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.
What is being reacted in this stage is the "leftover" of the negative image, that is, a positive image. As the colour development progresses, metallic silver image is formed, but more importantly, the colour developing agent is oxidised. Oxidised colour developer molecules react with the couplers to form colour dyes in situ.
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]
The technique can illustrate emotions ranging from crowdedness, to power, to chaos, or even to movement in a photo. Positive photos often busy and active so that most of the focus is drawn towards the subject. It is important to note that positive space in photography is usually balanced with negative space to make an appealing composition.
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.
