A camera that takes and prints the photograph in one self-contained unit. For many decades, instant camera was synonymous with the Polaroid brand. For a while, Kodak offered an instant camera but was forced to stop production after Polaroid filed a patent infringement lawsuit. In the early 1980s, Fujifilm entered the instant camera market and has continued to offer products ever since.How It WorksWhen a picture is taken, cyan, magenta and yellow color layers in the film are exposed to light. When it is pulled out of the camera, rollers squeeze a chemical strip at the edge of the film over the surface, which reacts with chemicals in the film to cause it to develop.
