film format

A film format is a technical definition of a set of standard characteristics regarding the image capture of still film or the image capture and projection of motion picture film. In the latter case, it may also encompass audio parameters (though often not). These characteristics usually include the film gauge, pulldown method, lens anamorphosis (or lack thereof), and film gate or projector aperture dimensions, all of which need to be defined for photography as well as projection, as they may differ.

Unless otherwise noted, all formats were introduced by Kodak, who began allocating the number series in 1913. Before that, films were just identified by the name of the cameras they were intended for.

For roll holder means film for cartridge roll holders, allowing roll film to be used with cameras designed to use glass plates.

The primary reason there were so many different negative formats in the early days was that prints were made by contact, without use of an enlarger. The film format would thus be exactly the same as the size of the print -- so if you wanted large prints, you would have to use a large camera and corresponding film format.

Film speed is the measure of a photographic film's sensitivity to light. Stock with lower sensitivity (lower ISO speed rating) requires a longer exposure and is thus called a slow film, while stock with higher sensitivity (higher ISO speed rating) can shoot the same scene with a shorter exposure and is called a fast film.

I have seen the trailer its a scary movie and the man in it Jim Carrey discovers that he has found a clue the number 23 and he finds that a lot of numbers add up to it.
