Advanced Photo System, a camera and film system designed jointly by Kodak, Fuji, Nikon, Canon and Minolta. The film cartridge, with a slightly smaller film than 35 mm film, is as easy to load as a battery film as it slots effortlessly into a chamber on the camera, and can be exchanged for another film without having to finish the roll. It also has a status indictor on one end showing if the film is unused, partially used, used but unprocessed or processed. So you won't hand in an unexposed roll for processing or put a film through the camera twice and double expose everything. The system allows the photographer to have his settings recorded on the back of his prints, which is automatically done by the processing lab. Although a few APS SLR models were made by Canon and one other manufacturer, most APS cameras tend to be compact and easy to use, but they are often less versatile than 35mm cameras at equivalent price points. The APS system is now regarded as an interim product, used only by consumers, which was popular for a short time, until better compact cameras became available at affordable prices. Most manufacturers have discontinued production of APS cameras. APS film is still available here and there, and processing labs still accept APS film.

Advanced Photo System type-C should not be confused with the Advanced Photographic System (APS) camera/film system, since the former is digital and the latter is analogue. APS-C is a type of image sensor found in certain digital single lens reflex (DSLR) cameras. These sensors are smaller than the ones used for the conventional 36 mm x 24 mm (35 mm) sensor SLR cameras (also called full frame DSLR cameras). Being smaller causes a 1.x multiplier for the effect of the focal distance of the lenses, in comparison with the effect of those lenses on conventional 35 mm film SLR cameras or full frame digital SLR cameras. Several manufacturers produce cameras with an APS-C sensor and some even make lenses especially for them. These lenses are found in the Canon EF-S, Nikon DX, Pentax DA and Sigma DC ranges, to name the most popular ones. The most common multiplier ratios are 1.6 (Canon), 1.5 (Nikon, Fuji, Sony, etc.), 1.3 (Canon). (1.3 crop sensors are also sometimes called APS-H.) Most manufacturers not only produce cameras with these cropped sensors, but also offer DSLR cameras with full frame sensors.
A new film format developed and introduced by Minolta, Nikon, Fuji, Kodak and Canon back in 1996.The system was developed to make it easier to load into cameras and offers many processing benefits. For more information, see "APS"
The base for APS film emulsions. Its a strong material that it accepts film emulsions evenly and, with a thickness of just 90 microns its 30% thinner than the acetate base used in conventional 35mm emulsions.
This is the manufacturers’ quoted focal length of the lens supplied with the camera. APS film and digital camera CCDs are smaller than conventional 35mm film so the indicated focal lengths are also smaller and should not be compared directly. For a direct comparison of APS and digital lenses look at the 35mm equivalent figures that are quoted.
Describes how much an imaging sensor has been cropped in relation to its full-frame equivalent. It always describes how many times larger the full-frame is in relation to the cropped sensor. Take an APS-C sensor with a crop factor of 1.6, for instance. This indicates the sensor is 60% of the size of a frame of 35mm film. The crop factor is used to calculate how much of the equivalent of the full-frame field of view the cropped sensor will have with a lens. In order to calculate this, one multiplies the focal length of the lens by the crop factor. A 1.6 crop-factor, for instance, will give a 100mm lens the same field of view as a 160mm lens on a full-frame camera.
A pattern on the base of APS film cartridges that tells the camera the film speed and number of exposures, so when loading a film you don't have to worry about getting it wrong. Or, in a more general sense, a data disc can be any disc with electronic files on it.
A rotating set of four icons on the base of an APS film cartridge that indicates what stage the film is at unexposed, partly-exposed, fully-exposed but not processed and processed.
APS films are coated with an invisible magnetic coating that doesn't affect picture quality but holds Information Exchange (IX) data which can be read by cameras and processing machinery. Data recorded could include the user's selected print format, date, time and information about the shooting conditions to helps the printing machine achieve optimum print quality. This is known as Print Quality Improvement (PQI).
Developed by Fujifilm for their Nexia APS films. The formulated grain structure is about one-half the size of conventional films and ensures consistent shape for exceptionally smooth, fine-grained prints.
An electronic flash has a maximum distance that it is capable of illuminating. There's also usually a close point where it will start to become too bright and overexpose the subject. The distance from the closest to the furthest point that it can illuminate is the flash range. The range can be increased by using a faster film or more sensitive CCD, and reduced by diffusing the light source using ND filters or material. The range quoted is usually based on using ISO 100 film or a CCD with equivalent sensitivity. APS cameras are, for some reason, quoted using ISO 200 film.
