Photographic paper is a paper coated with a light-sensitive chemical formula, like photographic film, used for making photographic prints. When photographic paper is exposed to light, it captures a latent image that is then developed to form a visible image; with most papers the image density from exposure can be sufficient to not require further development, aside from fixing and clearing, though latent exposure is also usually present. The light-sensitive layer of the paper is called the emulsion. The most common chemistry was based on silver halide but other alternatives have also been used.
An instant camera is a camera which uses self-developing film to create a chemically developed print shortly after taking the picture. Polaroid Corporation pioneered consumer-friendly instant cameras and film, and were followed by various other manufacturers.
In the processing of photographic films, plates or papers, the photographic developer is one or more chemicals that convert the latent image to a visible image. Developing agents achieve this conversion by reducing the silver halides, which are pale-colored, into silver metal, which is black when in the form of fine particles. The conversion occurs within the gelatine matrix. The special feature of photography is that the developer acts more quickly on those particles of silver halide that have been exposed to light. When left in developer, all the silver halides will eventually be reduced and turn black. Generally, the longer a developer is allowed to work, the darker the image.
C-41 is a chromogenic color print film developing process introduced by Kodak in 1972, 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.
Instant film is a type of photographic film that was introduced by Polaroid Corporation to produce a visible image within minutes or seconds of the photograph's exposure. The film contains the chemicals needed for developing and fixing the photograph, and the camera exposes and initiates the developing process after a photo has been taken.
Cinecolor was an early subtractive color-model two-color motion picture process that was based upon the Prizma system of the 1910s and 1920s and the Multicolor system of the late 1920s and the 1930s. It was developed by William T. Crispinel and Alan M. Gundelfinger, and its various formats were in use from 1932 to 1955.
The SX-70 is a folding single lens reflex Land camera which was produced by the Polaroid Corporation from 1972 to 1981.
A film holder is a accessory that holds one or more pieces of photographic film, for insertion into a camera or optical scanning device such as a dedicated film scanner or a flatbed scanner with film scanning capabilities. The widest use of the term refers to a device that holds sheet film for use in large format cameras, but it can also refer to various interchangeable devices in medium format or even 135 film camera systems.
The Polaroid Model 20 "Swinger" was a popular Land Camera produced by the Polaroid Corporation between July 1965 and 1970. At $19.95 and weighing only 21 ounces (600 g), it was the first truly inexpensive instant camera, a fact that helped fuel its enormous popularity and made it one of the top-selling cameras of all time. The Swinger was especially successful in the youth market due to its low price, stylish appearance, catchy Meet the Swinger jingle, as well as getting the camera into drugstores. In fact, it was so successful that it became Polaroid's best selling product at the time, and increased their share in the new camera market.
Polaroid Type 55 film is a black-and-white peel-apart Polaroid film that yields both a positive print and a negative image that can be used to create enlargements.
Polacolor was the trade name of two very different color photography products developed by the Polaroid Corporation.
Color motion picture film refers both to unexposed color photographic film in a format suitable for use in a motion picture camera, and to finished motion picture film, ready for use in a projector, which bears images in color.
Redscale is a technique of shooting photographic film where the film is exposed from the wrong side, i.e. the emulsion is exposed through the base of the film. Normally, this is done by winding the film upside-down into an empty film canister. The name "redscale" comes because there is a strong color shift to red due to the red-sensitive layer of the film being exposed first, rather than last [the red layer is normally the bottom layer in C-41 film]. All layers are sensitive to blue light, so normally the blue layer is on top, followed by a filter. In this technique, blue light exposes the layers containing cyan and magenta dyes, but the layer containing yellow dye is left unexposed due to the filter. E-6 film has also been used for this technique.
Dye transfer is a continuous-tone color photographic printing process. It was used to print Technicolor films, as well as to produce paper colour prints used in advertising, or large transparencies for display.
In bipack color photography for motion pictures, two strips of black-and-white 35 mm film, running through the camera emulsion to emulsion, are used to record two regions of the color spectrum, for the purpose of ultimately printing the images, in complementary colors, superimposed on one strip of film. The result is a multicolored projection print that reproduces a useful but limited range of color by the subtractive color method. Bipack processes became commercially practical in the early 1910s when Kodak introduced duplitized film print stock, which facilitated making two-color prints.
Polaroid art is a type of alternative photography which consists of modifying an instant picture, usually while it is being developed. The most common types of Polaroid art are the emulsion lift, the Polaroid transfer and emulsion manipulation.
Photographic film is a strip or sheet of transparent film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast, and resolution of the film. Film is typically segmented in frames, that give rise to separate photographs.
The Polaroid Impulse is a camera produced by Polaroid Corporation between 1988 and 1994. The camera uses Polaroid's 600-series integral film. The Impulse is distinguished from Polaroid's other 600-series cameras by its always-on flash, binocular-style grips, larger viewfinder, and self-timer.
Polaroid B.V. is a Dutch photography and consumer electronics company, founded as a manufacturer of discontinued film for Polaroid Corporation instant cameras. The company produces new instant cameras under the Polaroid brand name as well as wireless speakers and other accessories.
