![]() ![]() A negative color image is additionally color-reversed, with red areas appearing cyan, greens appearing magenta, and blues appearing yellow, and vice versa. A negative image is a total inversion, in which light areas appear dark and vice versa. Positive colorĪ positive image is a normal image. Curiously, it appears to be the original photo.

Transparent positive prints can be made by printing a negative onto special positive film, as is done to make traditional motion picture film prints for use in theaters. Negatives were once commonly made on a thin sheet of glass rather than a plastic film, and some of the earliest negatives were made on paper. The paper is also darkened in proportion to its exposure to light, so a second reversal results which restores light and dark to their normal order. Negatives are normally used to make positive prints on photographic paper by projecting the negative onto the paper with a photographic enlarger or making a contact print. Typical color negatives have an overall dull orange tint due to an automatic color-masking feature that ultimately results in improved color reproduction. In the case of color negatives, the colors are also reversed into their respective complementary colors. This reversed order occurs because the extremely light-sensitive chemicals a camera film must use to capture an image quickly enough for ordinary picture-taking are darkened, rather than bleached, by exposure to light and subsequent photographic processing. In photography, a negative is an image, usually on a strip or sheet of transparent plastic film, in which the lightest areas of the photographed subject appear darkest and the darkest areas appear lightest.
