A positive image is a normal image. A negative image is a total inversion of a positive image, in which light areas appear dark and vice versa. A negative color image is additionally color reversed, with red areas appearing cyan, greens appearing magenta and blues appearing yellow. This sometimes can have a reverse effect and cause the greens to appear a reddish brown.
Film negatives usually also have much less contrast than the final images. This is compensated by the higher contrast reproduction by photographic paper or by increasing the contrast when scanning and post processing the scanned images.

Famous quotes containing the words negative and/or image:
“In a country where misery and want were the foundation of the social structure, famine was periodic, death from starvation common, disease pervasive, thievery normal, and graft and corruption taken for granted, the elimination of these conditions in Communist China is so striking that negative aspects of the new rule fade in relative importance.”
—Barbara Tuchman (1912–1989)
“O delicate walker, babbler, dialectician Fire,
O enemy and image of ourselves,”
—Louis MacNeice (1907–1963)
