The type of camera with self-developing film is known as instant camera. Polaroid Corporation makes the famous Polaroid cameras.

Based on the type of film used, Polaroid cameras can be classified. The older Polaroids used instant film roll. Roll films were of two types: Positive or developing agent and negative. These rolls were available in three sizes. Pack film was later used in cameras, in which the photographer has to pull the film from the camera for developing and subsequently the positive and the negative have to be peeled separately while developing. This Pack film was available initially in a rectangular format and later in square format. Subsequent Polaroids such as the once famous SX-70 model utilized a square format integral film, which had the developer, negative, fixer etc in the same film. Development of each exposure was automatic once the shot is taken.
