Matte (filmmaking)
Mattes are used in photography and special effects filmmaking to combine two or more image elements into a single, final image. Usually, mattes are used to combine a foreground image (e.g. actors on a set) with a background image (e.g. a scenic vista or a starfield with planets). In this case, the matte is the background painting. In film and stage, mattes can be physically huge sections of painted canvas, portraying large scenic expanses of landscapes. In film, the principle of a matte requires masking certain areas of the film emulsion to selectively control which areas are exposed. However, many complex special-effects scenes have included dozens of discrete image elements, requiring very complex use of mattes and layering mattes on top of one another. For an example of a simple matte, the director may wish to depict a group of actors in front of a store, with a massive city and sky visible above the store's roof. There would be two images—the actors on the set, and the imag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photography
Photography is the art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purp ...

American Society Of Cinematographers
The American Society of Cinematographers (ASC), founded in Hollywood in 1919, is a cultural, educational, and professional organization that is neither a labor union nor a guild. The society was organized to advance the science and art of cinematography and gather a wide range of cinematographers to discuss techniques and ideas and to advocate for motion pictures as a type of art form. Currently, the president of the ASC is Stephen Lighthill. Members use the post-nominal letters "ASC". On the 1920 film titled ''Sand'', cinematographer Joseph H. August, who was an original member of the ASC, became the first individual to have the "ASC" appear after his name on the onscreen credit. Only film cinematographers and special effect supervisors can become an ASC member. Basic requirements include being a director of photography for a minimum five out of the last eight years, having a high professional reputation and being recommended by three active or retired ASC members.

Analog Signal
An analog signal or analogue signal (see spelling differences) is any continuous signal representing some other quantity, i.e., ''analogous'' to another quantity. For example, in an analog audio signal, the instantaneous signal voltage varies continuously with the pressure of the sound waves. In contrast, a digital signal represents the original time-varying quantity as a sampled sequence of quantized values which imposes some bandwidth and dynamic range constraints on the representation. The term ''analog signal'' usually refers to electrical signals; however, mechanical, pneumatic, hydraulic and other systems may also convey or be considered analog signals. Representation An analog signal uses some property of the medium to convey the signal's information. For example, an aneroid barometer uses rotary position as the signal to convey pressure information. In an electrical signal, the voltage, current, or frequency of the signal may be varied to represent the information. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optical Printer
An optical printer is a device consisting of one or more film projectors mechanically linked to a movie camera. It allows filmmakers to re-photograph one or more strips of film. The optical printer is used for making special effects for motion pictures, or for copying and restoring film material. Common optical effects include fade outs and fade ins, dissolves, slow motion, fast motion, and matte work. More complicated work can involve dozens of elements, all combined into a single scene. History The first commercially available, although not mass produced, optical printer appeared in 1927 and was called the Depue & Vance Daylight Optical Printer. It was mainly used to reduce standard prints to 16mm and allowed for operation without a darkroom except from loading the positive film magazine. In 1918, the cinematographer Carl Gregory came upon a printer made by G. J. Badgley of New York, designed to produce copies of a standard film using domestic size film stock. Realizing the p ...

Alpha Compositing
In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. It is often useful to render picture elements (pixels) in separate passes or layers and then combine the resulting 2D images into a single, final image called the composite. Compositing is used extensively in film when combining computer-rendered image elements with live footage. Alpha blending is also used in 2D computer graphics to put rasterized foreground elements over a background. In order to combine the picture elements of the images correctly, it is necessary to keep an associated ''matte'' for each element in addition to its color. This matte layer contains the coverage information—the shape of the geometry being drawn—making it possible to distinguish between parts of the image where something was drawn and parts that are empty. Although the most basic operation of combining two images is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Non-linear Editing System
Non-linear editing is a form of offline editing for audio, video, and image editing. In offline editing, the original content is not modified in the course of editing. In non-linear editing, edits are specified and modified by specialized software. A pointer-based playlist, effectively an edit decision list (EDL), for video and audio, or a directed acyclic graph for still images, is used to keep track of edits. Each time the edited audio, video, or image is rendered, played back, or accessed, it is reconstructed from the original source and the specified editing steps. Although this process is more computationally intensive than directly modifying the original content, changing the edits themselves can be almost instantaneous, and it prevents further generation loss as the audio, video, or image is edited. A non-linear editing system (NLE) is a video editing (NLVE) program or application, or an audio editing (NLAE) digital audio workstation (DAW) system. These perform non-des ...

Motion Control
Motion control is a sub-field of automation, encompassing the systems or sub-systems involved in moving parts of machines in a controlled manner. Motion control systems are extensively used in a variety of fields for automation purposes, including precision engineering, micromanufacturing, biotechnology, and nanotechnology. The main components involved typically include a motion controller, an energy amplifier, and one or more prime movers or actuators. Motion control may be open loop or closed loop. In open loop systems, the controller sends a command through the amplifier to the prime mover or actuator, and does not know if the desired motion was actually achieved. Typical systems include stepper motor or fan control. For tighter control with more precision, a measuring device may be added to the system (usually near the end motion). When the measurement is converted to a signal that is sent back to the controller, and the controller compensates for any error, it becomes a Cl ...

Petro Vlahos
Petro Vlahos ( gr, Πέτρος Βλάχος; August 20, 1916 – February 10, 2013) was an American engineer and inventor, considered to be one of the pioneering scientific and technical innovators of the motion picture and television industries. He is remembered in particular for creating the Ultimatte process, which refined the colour process known as chroma keying (i.e. "bluescreening"). In recognition of his contributions, he was awarded multiple Oscars, as well as an Emmy Award. Early life Vlahos was born in Raton, New Mexico, the son of Greek immigrants. He showed an early aptitude for electronics and ham radio, and in 1941, he gained his Engineering degree from the University of California at Berkeley. He worked as a designer for Douglas Aircraft in World War II, and later as a radar engineer at Bell Laboratories. After the war, he moved to Hollywood and worked for MGM.

Academy Award For Best Visual Effects
The Academy Award for Best Visual Effects is an Academy Award given for the best achievement in visual effects. History of the award The Academy of Motion Picture Arts and Sciences first recognized the technical contributions of special effects to movies at its inaugural dinner in 1929, presenting a plaque for "Best Engineering Effects" to the first Best Picture Oscar winner, the World War I flying drama ''Wings''. Producer David O. Selznick, then production head at RKO Studios, petitioned the Academy Board of Governors to recognize the work of animator Willis O'Brien for his groundbreaking work on 1933's ''King Kong''. It was not until 1938 when a film was actually recognized for its effects work, when a "Special Achievement Award for Special Effects" was given to the Paramount film ''Spawn of the North''. The following year, "Best Special Effects" became a recognized category, although on occasion the Academy has chosen to honor a single film outright rather than nominate two ...
