Monochrome photography is photography where each position on an image can record and show a different amount of light (), but not a different color ().The majority of monochrome photographs produced today are black-and-white, either from a gelatin silver process, or as digital photography.
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.
In photography, toning is a method of altering the color of black-and-white photographs. In analog photography, it is a chemical process carried out on metal salt-based prints, such as silver prints, iron-based prints (cyanotype or Van Dyke brown), or platinum or palladium prints. This darkroom process cannot be performed with a color photograph.
Monochrome (black and white) photography was first exemplified by the daguerreotype in 1839 and later improved by other methods including: calotype, ambrotype, tintype, albumen print, and gelatin silver print.
The gelatin silver print is the most commonly used chemical process in black-and-white photography, and is the fundamental chemical process for modern analog color photography. As such, films and printing papers available for analog photography rarely rely on any other chemical process to record an image.
By similar techniques, special-purpose films can be made sensitive to the infrared (IR) region of the spectrum. [2] Nikon F100 analog camera during loading of 35mm film. In black-and-white photographic film, there is usually one layer of silver halide crystals.
Lenticular (additive): a black-and-white film which has been embossed on its base side with hundreds or thousands of tiny lenses is used for the original photography, base side forward and in conjunction with a segmented multicolored filter on the camera lens. As in mosaic processes, the result is an array of adjacent microscopic black-and ...
A hand-colored print of George Méliès' The Impossible Voyage (1904). The first film colorization methods were hand-done by individuals. For example, at least 4% of George Méliès' output, including some prints of A Trip to the Moon from 1902 and other major films such as The Kingdom of the Fairies, The Impossible Voyage, and The Barber of Seville were individually hand-colored by Elisabeth ...
