Photographic paper is a paper coated with a light-sensitive chemical formula, used for making photographic prints. When photographic paper is exposed to light it captures a latent image that is then developed to form a visible image. The light-sensitive layer of the paper is called the emulsion.
The print image is traditionally produced by interposing a photographic negative between the light source and the paper, either by direct contact with a large negative (forming a contact print) or by projecting the shadow of the negative onto the paper (producing an enlargement). The initial light exposure is carefully controlled to produce a gray scale image on the paper with appropriate contrast and gradation. Photographic paper may also be exposed to light using digital printers such as the LightJet, with a camera (to produce a photographic negative), by scanning a modulated light source over the paper, or by placing objects upon it (to produce a photogram).
Despite the introduction of digital photography, photographic papers and are still sold commercially. Photographic papers are manufactured in numerous standard sizes, paper weights and surface finishes. A range of emulsions are also available that differ in their light sensitivity, color response and the warmth of the final image. Color papers are also available for making color images.

Famous quotes containing the words photographic and/or paper:
“Sickness sensitizes man for observation, like a photographic plate.”
—Edmond De Goncourt (1822–1896)
“There’s a long story, my friend. I never did like the idea of sitting on newspapers. I did it once and all the headlines came off on my white pants. On the level, it actually happened. Nobody bought a paper that day. They just followed me around over town and read the news off the seat of my pants.”
—Robert Riskin (1897–1955)
