What do you mean by format picture and format background
Answers
Answer:
This list of film formats catalogs formats developed for shooting or viewing motion pictures, ranging from the Chronograph format from 1888, to mid-20th century formats such as the 1953 CinemaScope format, to more recent formats such as the 1992 MAX HD format. To be included in this list, the formats must all have been used in the field or for test shooting, and they must all use photo chemical images that are formed or projected on a film base, a transparent substrate which supports the photosensitive emulsion.
As well, the formats must have been used to make more than just a few test frames. The camera must be fast enough (in frames per second) to create an illusion of motion consistent with the persistence of vision phenomenon. The format must be significantly unique from other listed formats in regard to its image capture or image projection. The format characteristics should be clearly definable in several listed parameters (e. g., film gauge, aspect ratio, etc.).
