Negative (photography)

（重定向自Film negative）

Color positive picture (A) and negative (B), monochrome positive picture (C) and negative (D)

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. This reversed order occurs because of the extremely light-sensitive chemicals a camera film must use to capture an image quickly enough for ordinary picture-taking, which are darkened, rather than bleached, by exposure to light and subsequent photographic processing.
