Large format describes photographic films, view cameras (including pinhole cameras) and processes that use a film or digital sensor the size of 4 x 5 inches or larger. The most common formats are 4 × 5 and 8 × 10 inches. Uncommon formats include quarter-plate, 5 × 7 inches, and 11 × 14 inches. The Polaroid 20 × 24 inch Instant Camera is the largest format camera currently in common usage, and can be hired from Polaroid agents in various countries. Many well-known photographers have used the 235-pound, wheeled-chassis Polaroid. Large Format Motion Picture cameras made by IMAX and Iwerks use perforated 70mm film. Although this is not large format in a still picture sense, it is certainly considered so for motion picture.
Most large-format cameras have adjustable fronts and backs that allow the photographer to better control perspective and depth of field. Architectural and close-up photographers in particular benefit greatly from this ability. Based on the Scheimpflug principle, these adjustments make it possible to solve photographic problems, and create effects, that would be impossible with a conventional fixed-plane camera. Ansel Adams' photographs demonstrate how the use of front (lens plane) and back (film plane) adjustments can secure great depth of field when using large format cameras.
A number of actions need to be taken when using a large format camera, resulting in a more contemplative photographic style. For example, film loading using double-sided Film Holders requires a changing bag or darkroom (although users of the most common format, 4 × 5, may now use Ready-Load pre-packaged film, which is more convenient than loading film holders). A tripod is essential for most view camera work. The scene is composed and then a film holder is slotted into the camera back prior to exposure. A separate Polaroid back using instant film is used by some photographers, allowing previewing of the composition, correctness of exposure and depth of field before committing to film to be developed later. Failure to "polaroid" an exposure risks discovery later, at the time of film development, that there was an error in camera setup.

RT @Pete_Brown: the HD video format is killing large lcd monitors. It seems like 3/4 of them are 1920x1080. I want my other 120 pixels!
