Color transparencies are an example of positive photography: the range of colors presented in the medium is limited by the tonal range of the original image (dark and light areas correspond). It is opposed to a negative where colors and luminance are reversed: this is due to the chemical or electrical processes involved in recording the scene ...
Non-digital photographs are produced with a two-step chemical process. In the two-step process, the light-sensitive film captures a negative image (colors and lights/darks are inverted). To produce a positive image, the negative is most commonly transferred ('printed') onto photographic paper. Printing the negative onto transparent film stock ...
A negative image on film is traditionally used to photographically create a positive image on a paper base, known as a print, either by using an enlarger or by contact printing. Before the emergence of digital photography , photographs on film had to be developed to produce negatives or projectable slides, and negatives had to be printed as ...
The ambrotype, also known as a collodion positive in the UK, is a positive photograph on glass made by a variant of the wet plate collodion process. Following the invention of daguerreotypes, cheaper than the French invention, ambrotypes came to replace them. Like a print on paper, it is viewed by reflected light.
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. [1]

The image as a whole therefore appeared to be a dull-toned positive. [5] [page needed] [6] This ability to employ underexposed images allowed shorter exposure times to be used, a great advantage in portraiture. To obtain as light-toned an image as possible, potassium cyanide was normally employed as the photographic fixer. It was perhaps the ...
