Photographic paper is different from regular paper in that it has special chemicals in it that react to light when a photographic film negative is projected on it in a darkroom, causing the picture to appear on it and then be "fixed" by use of other chemicals that make the image permanent and remove light sensitivity that would destroy it once the paper is exposed to normal lighting.
