Color Photography

Color photography is photography that uses media capable of representing colors, which are traditionally produced chemically during the photographic processing phase. By contrast, black-and-white (monochrome) photography records only a single channel of luminance (brightness) and uses media capable only of showing shades of gray.

In color photography, light-sensitive chemicals or electronic sensors 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 together 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).

Monochrome images which have been "colorized" by tinting selected areas by hand or mechanically or with the aid of a computer are "colored photographs," not "color photographs." Their colors are not dependent on the actual colors of the objects photographed and may be very inaccurate or completely imaginary.

Famous quotes containing the words photography and/or color:

    Too many photographers try too hard. They try to lift photography into the realm of Art, because they have an inferiority complex about their Craft. You and I would see more interesting photography if they would stop worrying, and instead, apply horse-sense to the problem of recording the look and feel of their own era.
    Jessie Tarbox Beals (1870–1942)

    Rain falls into the open eyes of the dead
    Again again with its pointless sound
    When the moon finds them they are the color of everything
    William Stanley Merwin (b. 1927)
