Digital Master
{{For, the Sony product line called DigitalMaster, DVCAM A digital master is an image, PDF file, digital recording or another digital asset preserved as the "original" for the purpose of archival storage, reuse and re-expression. For images, it is the digital analogue to a photographic negative. As the master from which variations for specific uses can be derived, the digital master may be in the form of its initial capture (like an unretouched photograph) or in a form that has been somehow enhanced, reformatted or edited (like a manipulated photo or a completed film). See also * Audio mastering, a form of audio post-production * Digital remastering, the quality enhancement of sound and/or picture to a previously existing recording * Dynamic imaging, the amalgamation of digital imaging, image editing, and workflow automation * Digital cinema, the use of digital technology to distribute or project motion picture A film also called a movie, motion picture, moving pictur ...

Image
An image is a visual representation of something. It can be two-dimensional, three-dimensional, or somehow otherwise feed into the visual system to convey information. An image can be an artifact, such as a photograph or other two-dimensional picture, that resembles a subject. In the context of signal processing, an image is a distributed amplitude of color(s). In optics, the term “image” may refer specifically to a 2D image. An image does not have to use the entire visual system to be a visual representation. A popular example of this is of a greyscale image, which uses the visual system's sensitivity to brightness across all wavelengths, without taking into account different colors. A black and white visual representation of something is still an image, even though it does not make full use of the visual system's capabilities. Images are typically still, but in some cases can be moving or animated. Characteristics Images may be two or three-dimensional, such as a ph ...

Image Editing
Image editing encompasses the processes of altering images, whether they are digital photographs, traditional photo-chemical photographs, or illustrations. Traditional analog image editing is known as photo retouching, using tools such as an airbrush to modify photographs or editing illustrations with any traditional art medium. Graphic software programs, which can be broadly grouped into vector graphics editors, raster graphics editors, and 3D modelers, are the primary tools with which a user may manipulate, enhance, and transform images. Many image editing programs are also used to render or create computer art from scratch. The term “image editing” usually refers only to the editing of 2D images, not 3D ones. Basics of image editing Raster images are stored in a computer in the form of a grid of picture elements, or pixels. These pixels contain the image's color and brightness information. Image editors can change the pixels to enhance the image in many ways ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motion Picture Film
Film stock is an analog medium that is used for recording motion pictures or animation. It is recorded on by a movie camera, developed, edited, and projected onto a screen using a movie projector. It is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast and resolution of the film.Karlheinz Keller et al. "Photography" in Ullmann's Encyclopedia of Industrial Chemistry, 2005, Wiley-VCH, Weinheim. The emulsion will gradually darken if left exposed to light, but the process is too slow and incomplete to be of any practical use. Instead, a very short exposure to the image formed by a camera lens is used to produce only a very slight chemical change, proportional to the amount of light absorbed by each crystal. This creates an invisible latent image in the emulsion, which can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motion Picture
A film also called a movie, motion picture, moving picture, picture, photoplay or (slang) flick is a work of visual art that simulates experiences and otherwise communicates ideas, stories, perceptions, feelings, beauty, or atmosphere through the use of moving images. These images are generally accompanied by sound and, more rarely, other sensory stimulations. The word "cinema", short for cinematography, is often used to refer to filmmaking and the film industry, and to the art form that is the result of it. Recording and transmission of film The moving images of a film are created by photography, photographing actual scenes with a movie camera, motion-picture camera, by photographing drawings or miniature models using traditional animation techniques, by means of computer-generated imagery, CGI and computer animation, or by a combination of some or all of these techniques, and other visual effects. Before the introduction of digital production, series of still imag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video Projector
A video projector is an image projector that receives a video signalling (telecommunication), signal and projects the corresponding image on a projection screen using a lens (optics), lens system. Video projectors use a very bright ultra-high-performance lamp (a special mercury arc lamp), Xenon arc lamp, LED or solid state blue, RB, RGB or remote fiber optic RGB lasers to provide the illumination required to project the image, and most modern ones can correct any curves, blurriness, and other inconsistencies through manual settings. If a blue laser is used, a phosphor wheel is used to turn blue light into white light, which is also the case with white LEDs. (White LEDs do not use lasers.) A wheel is used in order to prolong the lifespan of the phosphor, as it is degraded by the heat generated by the laser diode. Remote fiber optic RGB laser racks can be placed far away from the projector, and several racks can be housed in a single, central room. Each projector can use up to two ra ...

Film Distributor
A film distributor is responsible for the Film promotion, marketing of a film. The distribution company may be the same with, or different from, the production company. Distribution deals are an important part of financing a film. The distributor may set the film release, release date of a film and the method by which a film is to be exhibited or made available for viewing; for example, directly to the public either theatrically or for home viewing (DVD, Video on demand, video-on-demand, download, television programs through broadcast syndication etc.). A distributor may do this directly, if the distributor owns the theaters or film distribution networks, or through theatrical exhibitors and other sub-distributors. A limited distributor may deal only with particular products, such as DVDs or Blu-ray, or may act in a particular country or market. The primary distributor will often receive credit in the film's Billing (filmmaking), credits, one sheet or other marketing material. Th ...

Digital Cinema
Digital cinema refers to adoption of digital technology within the film industry to distribute or project motion pictures as opposed to the historical use of reels of motion picture film, such as 35 mm film. Whereas film reels have to be shipped to movie theaters, a digital movie can be distributed to cinemas in a number of ways: over the Internet or dedicated satellite links, or by sending hard drives or optical discs such as Blu-ray discs. Digital movies are projected using a digital video projector instead of a film projector, are shot using digital movie cameras and edited using a non-linear editing system (NLE). The NLE is often a video editing application installed in one or more computers that may be networked to access the original footage from a remote server, share or gain access to computing resources for rendering the final video, and to allow several editors to work on the same timeline or project. Alternatively a digital movie could be a film reel that ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Workflow
A workflow consists of an orchestrated and repeatable pattern of activity, enabled by the systematic organization of resources into processes that transform materials, provide services, or process information. It can be depicted as a sequence of operations, the work of a person or group, the work of an organization of staff, or one or more simple or complex mechanisms. From a more abstract or higher-level perspective, workflow may be considered a view or representation of real work. The flow being described may refer to a document, service, or product that is being transferred from one step to another. Workflows may be viewed as one fundamental building block to be combined with other parts of an organization's structure such as information technology, teams, projects and hierarchies. Historical development The development of the concept of a workflow occurred above a series of loosely defined, overlapping eras. Beginnings in manufacturing The modern history of workflows ca ...

Digital Imaging
Digital imaging or digital image acquisition is the creation of a digital representation of the visual characteristics of an object, such as a physical scene or the interior structure of an object. The term is often assumed to imply or include the processing, compression, storage, printing and display of such images. A key advantage of a digital image, versus an analog image such as a film photograph, is the ability to digitally propagate copies of the original subject indefinitely without any loss of image quality. Digital imaging can be classified by the type of electromagnetic radiation or other waves whose variable attenuation, as they pass through or reflect off objects, conveys the information that constitutes the image. In all classes of digital imaging, the information is converted by image sensors into digital signals that are processed by a computer and made output as a visible-light image. For example, the medium of visible light allows digital photography (in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Recording
In digital recording, an audio or video signal is converted into a stream of discrete numbers representing the changes over time in air pressure for audio, or chroma and luminance values for video. This number stream is saved to a storage device. To play back a digital recording, the numbers are retrieved and converted back into their original analog audio or video forms so that they can be heard or seen. In a properly matched analog-to-digital converter (ADC) and digital-to-analog converter (DAC) pair the analog signal is accurately reconstructed per the constraints of the Nyquist–Shannon sampling theorem dependent on the sampling rate and quantization error dependent on the audio or video bit depth. Because the signal is stored digitally, assuming proper error detection and correction, the recording is not degraded by copying, storage or interference.

Dynamic Imaging
Dynamic imaging is the amalgamation of digital imaging, image editing, and workflow automation. It is used to automate the creation of images by zooming, panning, colorize and performing other image processing and color management operations on a copy of a digital master. Categories Dynamic imaging technology falls into three categories: * Script dynamic imaging: A shell script is used to automate repeated tasks in programs. * Batch dynamic imaging (IIP based imaging server): An engine is used in batch processing of images. * Real-time dynamic imaging: An imaging server An image server is web server software which specializes in delivering (and often modifying) images. However, not all image servers support HTTP or can be used on web sites. While traditional web servers generally supply clients with static copi ... allows realtime rendering of images, text, logos and colorization based on internal and external data sources.

Digital Remastering
Remaster refers to changing the quality of the sound or of the image, or both, of previously created recordings, either audiophonic, cinematic, or videographic. The terms digital remastering and digitally remastered are also used. Mastering A master is the definitive recording version that will be replicated for the end user, commonly into other formats (e.g. LP records, CDs, DVDs, Blu-rays). A batch of copies is often made from a single original master recording, which might itself be based on previous recordings. For example, sound effects (e.g. a door opening, punching sounds, falling down the stairs, a bell ringing) might have been added from copies of sound effect tapes similar to modern sampling to make a radio play for broadcast. Problematically, several different levels of masters often exist for any one audio release. As an example, examine the way a typical music album from the 1960s was created. Musicians and vocalists were recorded on multi-track tape. This tape w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
