Night-for-night
In cinematography, night-for-night filming is the practice of actually filming night scenes at night. In the early days of cinema, before the invention of the proper lighting systems, night scenes were filmed "day-for-night"—that is, they were filmed during the day, and the film was "corrected", either with a polarized lens on the movie camera, or via a variety of post-production techniques. Day-for-night shooting is still used in low-budget films. The American television producer Quinn Martin Quinn Martin (born Irwin Martin Cohn; May 22, 1922 – September 5, 1987) was an American television producer. He had at least one television series running in prime time every year for 21 straight years (from 1959 to 1980). Martin is a mem ... was known for heavily utilizing night-for-night filming.

Cinematography
Cinematography (from ancient Greek κίνημα, ''kìnema'' "movement" and γράφειν, ''gràphein'' "to write") is the art of motion picture (and more recently, electronic video camera) photography. Cinematographers use a lens to focus reflected light from objects into a real image that is transferred to some image sensor or light-sensitive material inside a movie camera. These exposures are created sequentially and preserved for later processing and viewing as a motion picture. Capturing images with an electronic image sensor produces an electrical charge for each pixel in the image, which is electronically processed and stored in a video file for subsequent processing or display. Images captured with photographic emulsion result in a series of invisible latent images on the film stock, which are chemically " developed" into a visible image. The images on the film stock are projected for viewing the same motion picture. Cinematography finds uses in many fields of ...

Day-for-night
Day for night is a set of cinematic techniques used to simulate a night scene while filming in daylight. It is often employed when it is too difficult or expensive to actually shoot during nighttime. Because both film stocks and digital image sensors lack the sensitivity of the human eye in low light conditions, night scenes recorded in natural light, with or without moonlight, may be underexposed to the point where little or nothing is visible. This problem can be avoided by using daylight to substitute for darkness. When shooting day for night, the scene is typically underexposed in-camera or darkened during post-production, with a blue tint added. Additional effects are often used to heighten the impression of night. As film stocks and video cameras have improved in light sensitivity, shooting day for night has become less common in recent years. Techniques During the silent era of film, release prints were often tinted blue during night scenes to enhance the illusion. Althou ...

Polarization (waves)
Polarization (also polarisation) is a property applying to transverse waves that specifies the geometrical orientation of the oscillations. In a transverse wave, the direction of the oscillation is perpendicular to the direction of motion of the wave. A simple example of a polarized transverse wave is vibrations traveling along a taut string ''(see image)''; for example, in a musical instrument like a guitar string. Depending on how the string is plucked, the vibrations can be in a vertical direction, horizontal direction, or at any angle perpendicular to the string. In contrast, in longitudinal waves, such as sound waves in a liquid or gas, the displacement of the particles in the oscillation is always in the direction of propagation, so these waves do not exhibit polarization. Transverse waves that exhibit polarization include electromagnetic waves such as light and radio waves, gravitational waves, and transverse sound waves (shear waves) in solids. An electromagnetic wa ... [...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] |
Post-production
Post-production is part of the process of filmmaking, video production, audio production, and photography. Post-production includes all stages of production occurring after principal photography or recording individual program segments. The first part of the post-production process is the traditional non-linear (analog) film editing at the outset of post-production has mostly been replaced by digital or video editing software that operates as a non-linear editing (NLE) system. The advantage of being able to have this non-linear capacity is in the flexibility for editing scenes out of order, making creative changes at will, carefully shaping the film in a thoughtful, meaningful way for emotional effect. Once the production team is satisfied with the picture editing, the picture editing is said to be "locked." At this point begins the turnover process, where the picture is prepared for lab and color finishing and the sound is "spotted" and turnover to the composer and sound de ...

Quinn Martin
Quinn Martin (born Irwin Martin Cohn; May 22, 1922 – September 5, 1987) was an American television producer. He had at least one television series running in prime time every year for 21 straight years (from 1959 to 1980). Martin is a member of the Television Hall of Fame, having been inducted in 1997. Early life Born on May 22, 1922, in New York City, Martin was the second of two children. His father, Martin G. Cohn, Martin Goodman Cohn, was a film editor and producer at the studios of Metro Goldwyn Mayer; his mother was Anna Messing Cohn. He was of Jewish descent. From the age of 4, he was raised in Los Angeles, California. He graduated from Fairfax High School (Los Angeles), Fairfax High School, then served five years in the United States Army during World War II, enlisting in the Signal Corps (United States Army), Signal Corps at Fort MacArthur in San Pedro, California on September 10, 1940, and achieving the rank of sergeant. He later changed his name to Quinn Martin. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
