Instant film is a type of photographic film introduced by Polaroid to be used in an instant camera (and, with accessory hardware, with many professional film cameras). The film contains the chemicals needed for developing and fixing the photo, and the instant camera exposes and initiates the developing process after a photograph has been taken. In 1972, Polaroid introduced integral film, which incorporated timing and receiving layers to automatically develop and fix the photo without any intervention from the photographer. In February 2008, Polaroid announced it would cease production of all instant film; Sales of chemical film by all makers have dropped by at least 25% per year since 2000, but a new birth of interest around particular The Impossible Project's new films is seeing a rise in its popularity amongst creative artists.
