Black-and-white''This article is about the term as used in media and computing; for more specific uses, see Black and White.'' ---- ''Black-and-white'' is a broad adjectival term used to describe a number of forms of visual technology. Most forms of visual technology start out in black and white, then slowly evolve into color as technology progresses. "Black-and-white" as a description is also something of a misnomer, for in addition to black and white most of these media included varying shades of grey. Further, the original stock of many early photographic and film formats were in sepia tone, which gave a richer, more subtle shading than reproductions in plain black-and-white, although less so than color. == Media == Some popular black-and-white media forms of the past include: *Film and animated cartoons. While some color film processes (including hand coloring) were experimented with and in limited use from the earliest days of the motion picture, the switch from films almost always being in black-and-white to almost always being in color was a gradual process mostly taking place from the 1930s to the 1950s, with higher budget pictures being in color earlier. *Photography was black-and-white or shades of sepia. Color photography was originally rare and expensive, and early on often less true to life. Color photography became much more common in middle of the 20th century. *Television was originally broadcast in black-and-white. Some color broadcasts began in the 1950s, with color becoming common in western industrialized nations during the 1960s and 1970s. The United States upgraded to the color standard between 1964 and 1967, while the United Kingdom settled on an official color system in November 1969. Australia would keep airing black-and-white broadcasts until 1975. *Some newspapers were black-and-white until the late 1970s (and still remain largely colorless); the New York Times and Washington Post remained in black-and-white until the 1990s, some claiming USA Today was the major impetus for the change. *''Jet Magazine'' magazine was either all or mostly black-and-white until the end of the 20th century, when it became all-color. Today black-and-white Mass media often has a "nostalgic," historic, or anachronism feel to it. Some modern film directors will occasionally shoot movies in black-and-white because they believe it captures their vision better. For example, the 1998 Woody Allen film ''Celebrity (movie)'' was shot entirely in black-and-white. Other films, such as ''Pleasantville (movie)'' and ''The Wizard of Oz (1939 movie)'' play with the concept of the black-and-white anachronism, using it to selectively portray scenes and characters who are either more outdated or dull than the characters and scenes shot in full-color. This manipulation of color appears in the film ''Sin City (movie)'' and the occasional television commercial. The term black-and-white is sometimes used in a derogatory sense, with full-color being regarded as more desirable. == Computing == Most personal computers had monochrome (black-and-white, black and green, or black and amber) Computer monitor until the late 1980s. In computing terminology black-and-white is often used to refer to an image consisting ''solely'' of black or white pixels; what would normally be called a black-and-white image is more accurately referred to in this context as ''grayscale'' or ''greyscale'', ie an image containing shades of grey. ==External links== [http://www.cambridgeincolour.com/tutorials/color-black-white.htm Converting a Color Photo Into Black and White]: includes interactive photos showing how it works, a background on color filter use in traditional film photography, and a comparison of digital conversion techniques Photographic terms Black-and-whiteIsn't it also used for Apartheid? :"I'm not saying that joke was obvious, but there are hitherto undiscovered tribes in the depths of the Amazon Rainforest who knew you were going to say that" :-- The Young Ones (television series) :...... User:Lee M 23:47, 18 Aug 2003 (UTC) Here is an interesting thing: (Please read slowly and carefully) You always know about how to distinguish color from black and white, of course. But why?? This is because black (0 0 0) and white (255 255 255) are 2 of only 6 colors that all colors are based on, the others are red (255 0 128,) yellow (255 255 0,) green (0 255 128,) and blue (0 0 255.) These 6 colors are the psychological primary colors. (Look up primary colors at http://dictionary.reference.com if you want to see how they are used.) This set of colors is much less well-known than the traditional primary colors (red, yellow, and blue) or the light primary colors (red, green, and blue,) and was first identified in 1874 by a theory called the opponent color theory. All colors can be thought of as being on 3 scales, the "black-white" scale, the "blue-yellow" scale, and the "red-green" scale. This explains why some colors can be mixed to form new colors, but certain pairs "cannot" (actually, they can; the mixture is just gray.) Colors that produce gray when mixed are called complementary colors. Black and white are complements, as are red and green, as well as blue and yellow. I've been wondering if anyone can soon be creative and make some pictures entirely in either blue and yellow or red and green. Please note the following rules: For making pictures in blue and yellow, the colors you use are the exact same blue and yellow that most people familiar with RGB think of: 255 255 0 for yellow and 0 0 255 for blue. For making pictures in red and green, you must use colors that are slightly less yellow than the "red" and "green" that most people familiar with RGB think of: 255 0 128 for red and 0 255 128 for green. The colors that are used as "red" and "green" are actually somewhat orange-ish and lime-ish.
