Rotary Disc Shutter
A rotary disc shutter is a type of shutter. It is notably used in motion picture cameras. Rotary shutters are semicircular discs that spin in front of the film gate, alternately allowing light from the lens to strike the film, or blocking it. Details Rotary shutters are semicircular discs that spin in front of the film gate, alternately allowing light from the lens to strike the film, or blocking it. When blocking the light, the exposed portion of the film is advanced, and another, pristine frame is moved into position. The spinning disc then exposes the new frame of film. The nature of light-sensitive film requires a shutter to block the light and prevent ''smearing'' of the image as the film is advanced through the camera. Digital sensors do not require a rotary shutter, although some high-end digital cinema cameras do have them. Some rotary shutters utilize mirrors (or mirrored surfaces) so that when the shutter is in its ''closed'' position, light from the lens is redirected ...

Moviecam Schematic Animation
Moviecam is a motion picture equipment company specializing in movie camera systems for 35 mm film. Moviecam is a motion picture Large Format Lens series released by ARRI Rental in 2021. There are 10 prime lenses ranging from 16mm to 135mm, all T2 except 100mm and 135mm T2.8. History Originally started in Vienna, Austria as an in-house project of Fritz Gabriel Bauer and Walter Kindler's Moviegroup film production company in the late 1960s, the amount of research and development needed to create a new and modern motion picture camera system from scratch led to the formal creation of Moviecam as an independent corporate entity in 1976. Although only three camera models ( SuperAmerica, Compact, and SL) were produced in significant quantities for international usage, the high-quality camera design, simplicity of usage compared to the contemporary models of Arri and Panavision, and integration of modern and pioneering camera features led to widespread usage in the film industry ...

Depth Of Field
The depth of field (DOF) is the distance between the nearest and the farthest objects that are in acceptably sharp focus (optics), focus in an image captured with a camera. See also the closely related depth of focus. Factors affecting depth of field For cameras that can only focus on one object distance at a time, depth of field is the distance between the nearest and the farthest objects that are in acceptably sharp focus in the image. "Acceptably sharp focus" is defined using a property called the "circle of confusion". The depth of field can be determined by focal length, distance to subject (object to be imaged), the acceptable circle of confusion size, and aperture. Limitations of depth of field can sometimes be overcome with various techniques and equipment. The approximate depth of field can be given by: \text \approx \frac for a given maximum acceptable circle of confusion , focal length , f-number , and distance to subject . As distance or the size of the acc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shutter Speed
In photography, shutter speed or exposure time is the length of time that the film or digital sensor inside the camera is exposed to light (that is, when the camera's shutter (photography), shutter is open) when taking a photograph. The amount of light that reaches the Photographic film, film or image sensor is proportional to the exposure time. of a second will let half as much light in as . Introduction The camera's shutter speed, the lens's aperture or f-stop, and the scene's luminance together determine the amount of light that reaches the film or sensor (the exposure (photography), exposure). Exposure value (EV) is a quantity that accounts for the shutter speed and the f-number. Once the sensitivity to light of the recording surface (either film or sensor) is set in numbers expressed in "Film speed#ISO, ISOs" (e.g. 200 ISO, 400 ISO), the light emitted by the scene photographed can be controlled through aperture and shutter-speed to match the film or sensor sensitivit ...

Olympus Pen F
The Olympus Pen F, Pen FT and Pen FV are very similar half-frame 35 mm single-lens reflex (SLR) cameras with interchangeable lenses produced by Olympus of Japan between 1963-1966 (Pen F), 1966-1972 (Pen FT) and 1967-1970 (Pen FV). The original Pen F has a double-stroke film advance and a distinctive logo rendered in a gothic font. The later Pen FT added a single-stroke film advance, and an uncoupled, integrated light meter, which uses a system of exposure numbers rather than f-stops. The exposure numbers were added to the aperture rings of later Pen F lenses; the rings could be pulled out and rotated to show conventional f-stops instead. A side-effect of the FT's light meter was a dimmer viewfinder. The Pen FV was essentially a Pen FT with the light meter deleted and the F's brighter viewfinder reinstated. ''Half frame'' means that the camera uses an 18×24 mm vertical (portrait A portrait is a painting, photograph, sculpture, or other artistic representation ...

Agfa Box Verschluss Offen
Agfa-Gevaert N.V. (Agfa) is a Belgian-German multinational corporation that develops, manufactures, and distributes analogue and digital imaging products, software, and systems. The company began as a dye manufacturer in 1867. In 1925, the company merged with several other German chemical companies to become chemicals giant IG Farben. IG Farben would go on to play major role in the economy of Nazi Germany. It extensively employed forced labour during the Nazi period, and produced Zyklon B poison gas used in the Holocaust. IG Farben was disestablished by the Allies in 1945. AGFA was reconstituted (as a subsidiary of Bayer) from the remnants of IG Farben in 1952. Agfa photographic film and cameras were once prominent consumer products. In 2004, the consumer imaging division was sold to a company founded via management buyout. AgfaPhoto GmbH, as the new company was called, filed for bankruptcy after a year, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shutter (photography)
In photography, a shutter is a device that allows light to pass for a determined period, exposing photographic film or a photosensitive digital sensor to light in order to capture a permanent image of a scene. A shutter can also be used to allow pulses of light to pass outwards, as seen in a movie projector or a signal lamp. A shutter of variable speed is used to control exposure time of the film. The shutter is constructed so that it automatically closes after a certain required time interval. The speed of the shutter is controlled either automatically by the camera based on the overall settings of the camera, manually through digital settings, or manually by a ring outside the camera on which various timings are marked. Camera shutter Camera shutters can be fitted in several positions: * Leaf shutters are usually fitted within a lens assembly (''central shutter''), or more rarely immediately behind (''behind-the-lens shutter'') or, even more rarely, in front of a lens, and s ...

Sync Sound
Sync sound (synchronized sound recording) refers to sound recorded at the time of the filming of movies. It has been widely used in movies since the birth of sound movies. History Even in the silent film era, films were shown with sounds, often with musical accompaniment by a pianist or an orchestra keeping time with the screen action. The first synchronization was a turning recording device marked with a white spot. As the white spot rotated, the cameraman hand-cranked the camera to keep it in sync with the recording. The method was then repeated for playback, but with the projectionist hand cranking the film projector. " Single-system" sound recorded sound optically to part of the original camera film, or magnetically to a stripe of magnetic coating along the film edge. " Double-system" sound used independent cameras and sound recorders. The first sync sound standard used recorders and cameras both powered by AC (alternating current) motors - essentially clock motors. Later ...

Saving Private Ryan
''Saving Private Ryan'' is a 1998 American epic war film directed by Steven Spielberg and written by Robert Rodat. Set in 1944 in Normandy, France, during World War II, it follows a group of soldiers, led by Captain John Miller ( Tom Hanks), on a mission to locate Private James Francis Ryan (Matt Damon) and bring him home safely after his three brothers have been killed in action. The cast also includes Edward Burns, Tom Sizemore and Jeremy Davies. Inspired by the books of Stephen E. Ambrose and accounts of multiple soldiers in a single family, such as the Niland brothers, being killed in action, Rodat drafted the script, and Paramount Pictures hired him to finish writing it. The project came to the attention of Hanks and Spielberg, whose involvement, due to their previous successes, secured the project's development. Spielberg wanted to make ''Saving Private Ryan'' as authentic as possible and hired Frank Darabont and Scott Frank to do uncredited rewrites based on re ...

Speed Ramping
Slow motion (commonly abbreviated as slow-mo or slo-mo) is an effect in film-making whereby time appears to be slowed down. It was invented by the Austrian priest August Musger in the early 20th century. This can be accomplished through the use of high-speed cameras and then playing the footage produced by such cameras at a normal rate like 30 fps, or in post production through the use of software. Typically this style is achieved when each film frame is captured at a rate much faster than it will be played back. When replayed at normal speed, time appears to be moving more slowly. A term for creating slow motion film is overcranking which refers to hand cranking an early camera at a faster rate than normal (i.e. faster than 24 frames per second). Slow motion can also be achieved by playing normally recorded footage at a slower speed. This technique is more often applied to video subjected to instant replay than to film. A third technique uses computer software post-processing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
