Images

See also: Deep color

In digital images, 48 bits per pixel, or 16 bits per each color channel (red, green and blue), is used for accurate processing. Such images do not look much better than 24-bit images, but the existence of more shades between colors (65,536 as opposed to 256) means that more operations can be performed on the image without risk of noticeable banding or posterization.

Famous quotes containing the word images:

    “For such an advanced civilization as ours to be without images that are adequate to it is as serious a defect as being without memory.”
    —Werner Herzog (b. 1942)

    “Disappointment, when it involves neither shame nor loss, is as good as success; for it supplies as many images to the mind, and as many topics to the tongue.”
    —Samuel Johnson (1709–1784)

    “It is not the literal past, the “facts” of history, that shape us, but images of the past embodied in language.”
    —Brian Friel (b. 1929)
