Black-and-white in the context of "Film colorization"

Color photography (also spelled as colour photography in Commonwealth English) is photography that uses media capable of capturing and reproducing colors. By contrast, black-and-white or gray-monochrome photography records only a single channel of luminance (brightness) and uses media capable only of showing shades of gray.

In color photography, electronic sensors or light-sensitive chemicals record color information at the time of exposure. This is usually done by analyzing the spectrum of colors into three channels of information, one dominated by red, another by green and the third by blue, in imitation of the way the normal human eye senses color. The recorded information is then used to reproduce the original colors by mixing various proportions of red, green and blue light (RGB color, used by video displays, digital projectors and some historical photographic processes), or by using dyes or pigments to remove various proportions of the red, green and blue which are present in white light (CMY color, used for prints on paper and transparencies on film).

Color television (American English) or colour television (British English) is a television transmission technology that also includes color information for the picture, so the video image can be displayed in color on the television set. It improves on the monochrome or black-and-white television technology, which displays the image in shades of gray (grayscale). Television broadcasting stations and networks in most parts of the world transitioned from black-and-white to color broadcasting between the 1960s and the 1980s. The invention of color television standards was an important part of the history and technology of television.

Transmission of color images using mechanical scanners had been conceived as early as the 1880s. A demonstration of mechanically scanned color television was given by John Logie Baird in 1928, but its limitations were apparent even then. Development of electronic scanning and display made a practical system possible. Monochrome transmission standards were developed prior to World War II, but civilian electronics development was frozen during much of the war. In August 1944, Baird gave the world's first demonstration of a practical fully electronic color television display. In the United States, competing color standards were developed, finally resulting in the NTSC color standard that was compatible with the prior monochrome system. Although the NTSC color standard was proclaimed in 1953, and limited programming soon became available, it was not until the early 1970s that color television in North America outsold black-and-white units. Color broadcasting in Europe did not standardize on the PAL or SECAM formats until the 1960s.

Y′UV, also written YUV, is the color model found in the PAL analogue color TV standard. A color is described as a Y′ component (luma) and two chroma components U and V. The prime symbol (') denotes that the luma is calculated from gamma-corrected RGB input and that it is different from true luminance. Today, the term YUV is commonly used in the computer industry to describe colorspaces that are encoded using YCbCr.

In TV formats, color information (U and V) was added separately via a subcarrier so that a black-and-white receiver would still be able to receive and display a color picture transmission in the receiver's native black-and-white format, with no need for extra transmission bandwidth.

Monochrome photography is photography where each position on an image can record and show a different amount of light (value), but not a different color (hue). The majority of monochrome photographs produced today are black-and-white, either from a gelatin silver process, or as digital photography. Other hues besides grey can be used to create monochrome photography, but brown and sepia tones are the result of older processes like the albumen print, and cyan tones are the product of cyanotype prints.

As monochrome photography provides an inherently less complete reproduction than color photography, it is mostly used for artistic purposes and certain technical imaging applications.

Photojournalism is journalism that uses images to tell a news story. It usually only refers to still images, but can also refer to video used in broadcast journalism. Photojournalism is distinguished from other close branches of photography (such as documentary photography, social documentary photography, war photography, street photography and celebrity photography) by having a rigid ethical framework which demands an honest and impartial approach that tells a story in strictly journalistic terms. Photojournalists contribute to the news media, and help communities connect with one other. They must be well-informed and knowledgeable, and are able to deliver news in a creative manner that is both informative and entertaining.

Similar to a writer, a photojournalist is a reporter, but they must often make decisions instantly and carry photographic equipment, often while exposed to significant obstacles, among them immediate physical danger, bad weather, large crowds, and limited physical access to their subjects.

Steamboat Willie is a 1928 American animated short film directed by Walt Disney and Ub Iwerks. It was produced in black-and-white by the Walt Disney Studio and was released by Pat Powers, under the name of Celebrity Productions. The cartoon is considered the public debut of Mickey Mouse and Minnie Mouse, although both appeared months earlier in a test screening of Plane Crazy and the then unreleased The Gallopin' Gaucho. Steamboat Willie is the third of Mickey's films to have been produced, but it is the first to have been distributed, because Disney had seen The Jazz Singer (1927) and became determined to produce one of the first fully synchronized sound cartoons.

Steamboat Willie is one of the first cartoons with synchronized sound, and one of the first cartoons to feature a fully post-produced soundtrack, which distinguished it from earlier sound cartoons, such as Inkwell Studios's Song Car-Tunes (1924–1926), My Old Kentucky Home (1926), and Van Beuren Studios's Dinner Time (1928). Disney believed that synchronized sound was the future of film.

Rawhide is an American Western television series starring Eric Fleming and Clint Eastwood. The show aired for eight seasons on the CBS network on Friday nights from January 9, 1959, to September 3, 1965, before moving to Tuesday nights from September 14, 1965, until December 7, 1965, with a total of 217 black-and-white episodes. The series was produced and sometimes directed by Charles Marquis Warren, who also produced early episodes of Gunsmoke. The show is remembered by many for its theme song, "Rawhide".

Spanning 7+1⁄2 years, Rawhide was the sixth-longest-running American television Western, exceeded only by Wagon Train, The Virginian, Bonanza, Death Valley Days, and Gunsmoke.

Hemp for Victory is a black-and-white United States government film made during World War II and released in 1942, explaining the uses of hemp, encouraging farmers to grow as much as possible. During World War II, the Marihuana Tax Act of 1937 was lifted briefly to allow for hemp fiber production to create ropes for the U.S. Navy but after the war marijuana reverted to its de facto illegal status.
