Film Gate
The film gate is the rectangular opening in the front of a motion picture camera where the film is exposed to light. The film gate can be seen by removing the lens and rotating the shutter out of the way. The film is held on a uniform plane at a calibrated distance in the gate by a pressure plate behind the film. Occasionally, as the film passes through the gate, friction can cause small slivers of celluloid to break off and stick in the side of the opening. These pieces of debris are called ''hairs''. A "hair in the gate" will remain in front of the film and create a dark line that sticks into the edge of the film frame as the camera is filming a shot. A hair can ruin the shot and is almost impossible to fix in post production without using modern digital removal techniques. Because of the intractability of this problem the focus puller (or 1st Assistant Camera) will open the camera and examine the gate for hairs at the end of each shot. Normally the assistant director will call ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Movie Camera
A movie camera (also known as a film camera and cine-camera) is a type of photographic camera that rapidly takes a sequence of photographs, either on an image sensor or onto film stock, in order to produce a moving image to project onto a movie screen. In contrast to the still camera, which captures a single image at a time, by way of an intermittent mechanism, the movie camera takes a series of images; each image is a ''frame'' of film. The strips of frames are projected through a movie projector at a specific frame rate (number of frames per second) to show a moving picture. When projected at a given frame rate, the persistence of vision allows the eyes and brain of the viewer to merge the separate frames into a continuous moving picture. History An interesting forerunner to the movie camera was the machine invented by Francis Ronalds at the Kew Observatory in 1845. A photosensitive surface was drawn slowly past the aperture diaphragm of the camera by a clockwork mechanism to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wet-transfer Film Gate
A wet-transfer film gate, or wet gate for short, is a film gate that is submerged in liquid, used for film restoration and archival scanning. Submerging the film in the gate in a liquid with a suitably matched refractive index reduces the effects of scratches on the film, by reducing the refractive effects which divert light that passes through the scratched part of the film. The liquid also acts to lift other forms of defects from the film. Perchloroethylene, a hazardous substance with multiple health and safety risks, is commonly used as the liquid medium in wet gate systems, requiring substantial precautions to be taken to ensure the safety of operators and to prevent pollution. Wet gate transfer is often preceded by other forms of film cleaning, such as the use of ultrasonic film cleaners.

Pin Registration
{{unreferenced, date=January 2014 A registration pin is a device intended to hold a piece of film, paper or other material in place during photographic exposure, copying or drawing. Registration pins are used in offset printing and cartography, to accurately position the different films or plates for multi-color work. In traditional, hand-drawn animation, the registration pins are often called pegs, and are attached to peg bar Also, in traditional, hand-taped printed circuit board artwork, usually at two or four times actual size. Sometimes on a single transparent base, usually mylar, with Layer 1 being on the front and Layer 2 being on the back, in red and green, respectively, for later "separation" into component parts using a process camera. Motion picture cameras and related applications In motion picture cameras, the pin(s) hold the film immovable during exposure. In certain "professional" motion picture cameras and "step" printers, there may be ''two'' registration pins: on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Film Formats
This list of motion picture film formats catalogues formats developed for shooting or viewing motion pictures, ranging from the Chronophotographe format from 1888, to mid-20th century Film format, formats such as the 1953 CinemaScope format, to more recent formats such as the 1992 IMAX 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 photochemical 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 movie projector, image projection. The format characteristics should be clearly definable in several listed parameter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zoom Lens
A zoom lens is a mechanical assembly of lens elements for which the focal length (and thus angle of view) can be varied, as opposed to a fixed-focal-length (FFL) lens (see prime lens). A true zoom lens, also called a parfocal lens, is one that maintains focus when its focal length changes. Most consumer zoom lenses do not maintain perfect focus, but are still parfocal designs. Most camera phones that are advertised as having optical zoom actually use a few cameras of different but fixed focal length, combined with digital zoom to make a hybrid system. The convenience of variable focal length comes at the cost of complexity – and some compromises on image quality, weight, dimensions, aperture, autofocus performance, and cost. For example, all zoom lenses suffer from at least slight, if not considerable, loss of image resolution at their maximum aperture, especially at the extremes of their focal length range. This effect is evident in the corners of the image, when displa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flashlight
A flashlight ( US, Canada) or torch ( UK, Australia) is a portable hand-held electric lamp. Formerly, the light source typically was a miniature incandescent light bulb, but these have been displaced by light-emitting diodes (LEDs) since the mid-2000s. A typical flashlight consists of the light source mounted in a reflector, a transparent cover (sometimes combined with a lens) to protect the light source and reflector, a battery, and a switch, all enclosed in a case. The invention of the dry cell and miniature incandescent electric lamps made the first battery-powered flashlights possible around 1899. Today, flashlights use mostly light-emitting diodes and run on disposable or rechargeable batteries. Some are powered by the user turning a crank, shaking the lamp, or squeezing it. Some have solar panels to recharge the battery. Flashlights are used as a light source outdoors, in places without permanently installed lighting, during power outages, or when a portable light sourc ...

Arri
The Arri Group () is a German manufacturer of motion picture film equipment. Based in Munich, the company was founded in 1917. It produces professional motion picture cameras, lenses, lighting and post-production equipment. Hermann Simon mentioned this company in his book ''Hidden Champions of the 21st Century'' as an example of a " hidden champion". The Arri Alexa camera system was used to film Academy Award winners for Best Cinematography including ''Hugo'', ''Life of Pi'', ''Gravity'', '' Birdman'', '' The Revenant'' and '' 1917''. History Early history Arri was founded in Munich, Germany on 12 September 1917 by August Arnold and Robert Richter as Arnold & Richter Cine Technik. The acronym ''Arri'' was derived from the initial two letters of the founders' surnames, ''Ar''nold and ''Ri''chter. In 1924, Arnold and Richter developed their first film camera, the small and portable Kinarri 35. In 1937, Arri introduced the world's first reflex mirror shutter in the Arriflex 35 c ...

Casanova (2005 Film)
''Casanova'' is a 2005 American romance film directed by Lasse Hallström starring Heath Ledger and loosely based on the life of Giacomo Casanova. The film premiered September 3, 2005, at the Venice Film Festival. It received mixed reviews and flopped at the box office. Plot A young woman tearfully leaves her son to live with his grandmother and promises to return for him someday. Several years later, in 1753, in Venice, Casanova is notorious for his promiscuity with women, his adventures being represented in puppet theatres around the city. The Doge, the ruler of the city, is a friend to Casanova, but cannot be too lenient on him as he wishes to avoid trouble with the Church. He warns Casanova to marry soon, or he will be exiled from the city. Casanova gets engaged to Victoria, famous for her virginity, to save himself from exile. Casanova later meets and falls in love with Francesca Bruni, who writes illegal feminist books under the pseudonym of a man, Bernardo Guardi, and ...

Cinematographer
The cinematographer or director of photography (sometimes shortened to DP or DOP) is the person responsible for the photographing or recording of a film, television production, music video or other live action piece. The cinematographer is the chief of the camera and light crews working on such projects and would normally be responsible for making artistic and technical decisions related to the image and for selecting the camera, film stock, lenses, filters, etc. The study and practice of this field is referred to as cinematography. The cinematographer is a subordinate of the director, tasked with capturing a scene in accordance with director’s vision. Relations between the cinematographer and director vary. In some instances, the director will allow the cinematographer complete independence, while in others, the director allows little to none, even going so far as to specify exact camera placement and lens selection. Such a level of involvement is less common when the director ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photographic Lens
A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically. There is no major difference in principle between a lens used for a still camera, a video camera, a telescope, a microscope, or other apparatus, but the details of design and construction are different. A lens might be permanently fixed to a camera, or it might be interchangeable with lenses of different focal lengths, apertures, and other properties. While in principle a simple convex lens will suffice, in practice a compound lens made up of a number of optical lens elements is required to correct (as much as possible) the many optical aberrations that arise. Some aberrations will be present in any lens system. It is the job of the lens designer to balance these and produce a desi ...

Camera Magazine
A camera magazine is a light-tight chamber or pair of chambers designed to hold film and move motion picture film stock before and after it has been exposed in the camera. In most movie cameras, the magazine is a removable piece of equipment. Many still photo cameras also have removable camera magazines. A film cartridge serves the same function, but is usually not reusable. Lengths In 16 mm filmmaking, most magazines are designed to accommodate up to 400 feet of film stock, which usually is the longest standard roll size available from film manufacturers (longer rolls can be made upon special request sometimes, but require special magazines). In 35mm filmmaking, there tend to be three common magazine types - 1000 foot magazines, which accommodate the longest standard roll size of 35 mm film; 400 foot magazines, which are often used when the camera is handheld in order to minimize the amount of weight upon the camera operator; and 400 foot Steadicam magazines, which are sp ...
