Advanced Photo System (APS) is a film format used in still photography. The film is 24 mm wide and has three image formats. The full image is captured on the film and an image recorded in one aspect ratio can be reprinted in either of the others. The format you prefer can be selected for individual images. APS film comes on a long plastic cartridge and is available in 40, 25 and 15 exposures.
The surface of the film is coated by a transparent magnetic coating and APS cameras use this information exchange system for recording information about each photo. One benefit with APS film is that it allows you to take unused film from the camera and use it later on. APS film was introduced in 1996 by several large companies and is generally used in point and shoot amateur cameras. APS film is made for APS cameras only and usually costs a few dollars a roll.
