<P> In black - and - white still photography, many photographers choose to shoot in solely black - and - white since the stark contrasts enhance the subject matter . </P> <P> Some formal photo portraits still use black - and - white . Many visual - art photographers use black - and - white in their work . </P> <P> As a form of censorship when movies and TV series are aired on Philippine television, many gory scenes are shown in black - and - white . Sometimes the exposure of innards or other scenes too bloody or gruesome are also blurred, not just rendered in monochrome, in compliance with Philippine broadcasting standards . </P> <P> Most computers had monochrome (black - and - white, black and green, or black and amber) screens until the late 1980s, although some home computers could be connected to television screens to eliminate the extra cost of a monitor . These took advantage of NTSC or PAL encoding to offer a range of colors from as low as 4 (IBM CGA) to 128 (Atari 800) to 4096 (Commodore Amiga). Early videogame consoles such as the Atari 2600 supported both black - and - white and color modes via a switch, as did some of the early home computers; this was to accommodate black - and - white TV sets, which would display a color signal poorly . (Typically a different shading scheme would be used for the display in the black - and - white mode .) </P>

When did black and white tv stop being made
