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:
“The negative cautions of science are never popular. If the experimentalist would not commit himself, the social philosopher, the preacher, and the pedagogue tried the harder to give a short- cut answer.”
—Margaret Mead (1901–1978)
“The vice named surrealism is the immoderate and impassioned use of the stupefacient image or rather of the uncontrolled provocation of the image for its own sake and for the element of unpredictable perturbation and of metamorphosis which it introduces into the domain of representation; for each image on each occasion forces you to revise the entire Universe.”
—Louis Aragon (1897–1982)
