Film format in the context of "Anamorphic format"

A film genre is a stylistic or thematic category for motion pictures based on similarities either in the narrative elements, aesthetic approach, or the emotional response to the film.

Drawing heavily from the theories of literary-genre criticism, film genres are usually delineated by "conventions, iconography, settings, narratives, characters and actors". One can also classify films by the tone, theme/topic, mood, format, target audience, or budget. These characteristics are most evident in genre films, which are "commercial feature films [that], through repetition and variation, tell familiar stories with familiar characters and familiar situations" in a given genre.

In optics, a circle of confusion (CoC) is an optical spot caused by a cone of light rays from a lens not coming to a perfect focus when imaging a point source. It is also known as disk of confusion, circle of indistinctness, blur circle, or blur spot.

In photography, the circle of confusion is used to determine the depth of field, the part of an image that is acceptably sharp. A standard value of CoC is often associated with each image format, but the most appropriate value depends on visual acuity, viewing conditions, and the amount of enlargement. Usages in context include maximum permissible circle of confusion, circle of confusion diameter limit, and the circle of confusion criterion.

135 film, more popularly referred to as 35 mm film or 35 mm, is a format of photographic film with a film gauge of 35 mm (1.4 in) loaded into a standardized type of magazine (also referred to as a cassette or cartridge) for use in 135 film cameras.

The term 135 was introduced by Kodak in 1934 as a designation for 35 mm film specifically for still photography, perforated with Kodak Standard perforations. It quickly grew in popularity, surpassing 120 film by the late 1960s to become the most popular photographic film size. Despite competition from formats such as 120, 828, 126, 110, and APS, it remains the most popular film size today.

Medium format has traditionally referred to a film format in photography and the related cameras and equipment that use film. Nowadays, the term applies to film and digital cameras that record images on media larger than the 24 mm × 36 mm (0.94 in × 1.42 in) used in 35 mm photography (though not including 127 sizes), but smaller than 4 in × 5 in (100 mm × 130 mm) (which is considered large format photography).

In digital photography, medium format refers either to cameras adapted from medium-format film photography uses or to cameras making use of sensors larger than that of a 35 mm film frame. Some of the benefits of using medium-format digital cameras include higher resolution sensors, better low-light capabilities compared to a traditional 35mm DSLR, and a wider dynamic range.

8 mm film is a motion picture film format in which the film strip is eight millimetres (0.31 in) wide. It exists in two main versions – the original standard 8 mm film, also known as regular 8 mm, and Super 8. Although both standard 8 mm and Super 8 are 8 mm wide, Super 8 has a larger image area because of its smaller and more widely spaced perforations.

There are also two other varieties of Super 8 – Single 8 mm and Straight-8 – that require different cameras but produce a final film with the same dimensions.

A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image. Fisheye lenses achieve extremely wide angles of view, well beyond any rectilinear lens. Instead of producing images with straight lines of perspective (rectilinear images), fisheye lenses use a special mapping ("distortion"; for example: equisolid angle, see below), which gives images a characteristic convex non-rectilinear appearance.

The term fisheye was coined in 1906 by American physicist and inventor Robert W. Wood based on how a fish would see an ultrawide hemispherical view from beneath the water (a phenomenon known as Snell's window). Their first practical use was in the 1920s for use in meteorology to study cloud formation giving them the name whole-sky lenses. The angle of view of a fisheye lens is usually between 100 and 180 degrees, although lenses covering up to 280 degrees exist (see below). Their focal lengths depend on the film format they are designed for.

Poseidon is a 2006 American action disaster film directed and co-produced by Wolfgang Petersen. It is the third film adaptation of Paul Gallico's 1969 novel The Poseidon Adventure, and a loose remake of the 1972 film. It stars Kurt Russell, Josh Lucas, and Richard Dreyfuss, with Emmy Rossum, Jacinda Barrett, Mike Vogel, Mía Maestro, Jimmy Bennett, and Andre Braugher in supporting roles.

It was produced by Virtual Studios and distributed by Warner Bros. Pictures. It had a simultaneous release in IMAX format. It was released on May 12, 2006, and it was criticized for its lackluster script but was praised for its visuals and was nominated at the 79th Academy Awards for Best Visual Effects. It grossed $181.7 million worldwide on a budget of $160 million; however, after the costs of promotion and distribution, Warner Bros. lost $70–80 million on the film, making it a box-office bomb as a result.

IMAX is a proprietary system of high-resolution cameras, film formats, film projectors, and theaters originally known for having very large screens with a tall aspect ratio (about 1.43:1) and steep stadium seating. More recently the aspect ratio has mostly become 1.90:1 (slightly wider than the 35 mm American and British widescreen standard for theatrical film of 1.85:1), with the 1.43:1 ratio format being available only in selected locations.

Graeme Ferguson, Roman Kroitor, Robert Kerr, and William C. Shaw were the co-founders of what would be named the IMAX Corporation (founded in September 1967 as Multiscreen Corporation, Ltd.), and they developed the first IMAX theatre projection standards in the late 1960s and early 1970s in Canada.
