Projection gauge is the film gauge (width) used for the release print. Projection aspect ratio is the image ratio determined by the ratio of the projection dimensions multiplied by the anamorphic power of the projection lenses (1× in the case of spherical lenses). This is also known as the intended theatrical aspect ratio. [1]
The common film aspect ratios used in cinemas are 1.85:1 and 2.39:1. [1] Two common videographic aspect ratios are 4:3 (1. 3:1), [a] the universal video format of the 20th century, and 16:9 (1. 7:1), universal for high-definition television and European digital television. Other cinematic and video aspect ratios exist, but are used infrequently.
Letter-boxing is the practice of transferring film shot in a widescreen aspect ratio to standard-width video formats while preserving the film's original aspect ratio. The resulting video-graphic image has mattes of empty space above and below it; these mattes are part of each frame of the video signal.
In film, a widescreen film is any film image with a width-to-height aspect ratio greater than 4:3 (1.33:1). For TV, the original screen ratio for broadcasts was in 4:3 (1.33:1). Largely between the 1990s and early 2000s, at varying paces in different countries, 16:9 (e.g. 1920×1080p 60p) widescreen displays came into increasingly common use by ...
These may also use other aspect ratios by cropping otherwise black bars at the top and bottom which result from cinema aspect ratios greater than 16∶9, such as 1.85 or 2.35 through 2.40 (dubbed "Cinemascope", "21∶9" etc.), while the standard horizontal resolution, e.g. 1920 pixels, is usually kept.
This aspect ratio was chosen as the geometric mean between 4:3 and 2.35:1, an average of the various aspect ratios used in film. [3] While 16:9 is well-suited for modern HDTV broadcasts , older 4:3 video has to be either padded with bars on the left and right side (pillarboxed), cropped or stretched, while movies shot with wider aspect ratios ...
A cartridge of Kodak 35 mm (135) film for cameras. A film format is a technical definition of a set of standard characteristics regarding image capture on photographic film for still images or film stock for filmmaking. It can also apply to projected film, either slides or movies. The primary characteristic of a film format is its size and shape.
Display aspect ratio; Paper size; Standard photographic print sizes; Motion picture film formats; Standard ad size; Pixel aspect ratio; Photolithography: the aspect ratio of an etched, or deposited structure is the ratio of the height of its vertical side wall to its width. HARMST High Aspect Ratios allow the construction of tall ...
