Film cassette loading feature in all Advanced Photo System cameras that virtually eliminates film-loading problems by automatically accepting the leaderless cassette and thrusting the film forward to the first unexposed frame without any user ...
Coding on a film cassette that is read by sensors in the camera's film chamber. The coding holds film characteristics such as the ISO rating and number of exposures.

Drop-in-Loading
Film cassette loading system that advances that new roll of film to the first frame when the camera is closed.
Since the 1980s, film cassettes have been marked with a DX encoding pattern for automatically setting the camera to use the correct sensitivity value for the film.
The ISO assigned to a film is labeled on the packaging material and on the film cassette or paper backing (fig. 2-1). Some types of black-and-white films are assigned one ISO number; others are assigned two or more.
The cine film was at first bought in bulk and loaded into the cameras in the dark room, but Leitz introduced a film cassette which could be loaded with 1.6 meter film in the darkroom which would be loaded in daylight into the camera when required.
CASSETTE - Better known as a film cassette, and sometimes called a cartridge, this is a light-proof container of metal or plastic into which film manufacturers (and bulk film loaders) roll strips of unexposed 35 mm film.
Cassette Elliptically shaped film cassette designed especially for the Advanced Photo System that serves as the sealed, leaderless container for all System film whether unexposed, exposed or processed. See also Film Status Indicators and NRIC.
Pattern printed on the side of a 35mm film cassette, which is used by the camera to sense the required ISO/ASA filmspeed setting. The film speed is sensed by means of electrical contacts pressing against the canister, so dirt can cause miss sensing.
DX coding. Coding printed onto film cassette denoting speed, length, etc. Read by sensors in the film compartment of most 35 mm cameras.
Dynamic range. The measure of the range of brightness levels that can be recorded by a digital sensor.
Most cameras now set the speed film automatically using DX coded film cassettes, but if there's a dial you can usually override.
Light-trapped film container used with 35 mm cameras.
Elliptically shaped film cassette designed especially for the Advanced Photo System that serves as the sealed, leaderless container for all System film whether unexposed, exposed or processed.
Many P&S have DX coding which automatically sets the film speed off the film cassette (that's what the black and silver checker pattern on all rolls of film are), but many give you the ability to set the film speed manually.
A pinhole camera may be made of a 126 film cassette and some cardboard. Descriptions and plans are found in Olpe (1993:16, 28-29).
Film speed dial. On the top plate usually to the left. Newer electronic cameras set the film speed from the DX code on the film cassette itself. You may be allowed to over ride this or maybe you won't.
Back printing - information printed on the back of a picture by the photofinisher. The system standard requires the printing of frame number, film cassette number and processing date automatically on the back of each Advanced Photo System print.
