RG Color Models
An RG color model is a dichromatic color model represented by red and green primary colors. The name of the pair of models comes from the initials of the two primary colors: red and green. The model may be either additive or subtractive. The primaries are added together in varying proportions to reproduce a linear gamut of colors, which can reproduce only a fraction of the colors possible with a trichromatic color space, such as for human color vision. The appearance of the color gamut changes depending on the primary colors chosen. When the primaries are complementary colors (e.g. red and cyan), then an equal mixture of the primaries will yield a neutral color (gray or white). However, when the primaries are ''not'' complementary colors, an equal mixture of the primaries will yield yellow, and a neutral color cannot be reproduced by the color space. Despite its shortcomings in color reproduction, these models were used in early color processes for films. Additive RG The additiv ...

Rg Chromaticity
The rg chromaticity space, two dimensions of the ''normalized RGB'', or rgb, space, is a chromaticity space, a two-dimensional color space in which there is no intensity information. In the RGB color space a pixel is identified by the intensity of red, green, and blue primary colors. Therefore, a bright red can be represented as (R,G,B) (255,0,0), while a dark red may be (40,0,0). In the normalized rgb space or rg space, a color is represented by the proportion of red, green, and blue in the color, rather than by the intensity of each. Since these proportions must always add up to a total of 1, we are able to quote just the red and green proportions of the color, and can calculate the blue value if necessary. Conversion between RGB and RG Chromaticity Given a color (R,G,B) where R, G, B = intensity of red, green and blue, this can be converted to color (r,g,b) where r, g, b imply the proportion of red, green and blue in the original color: r = \frac g = \frac b = \f ...

List Of Color Film Systems
This is a list of color film processes known to have been created for photographing and exhibiting motion pictures in color since the first attempts were made in the late 1890s. It is limited to "natural color" processes, meaning processes in which the color is photographically recorded and reproduced rather than artificially added by hand-painting, stencil coloring, or other arbitrary " colorization" methods. Legend *Process: the name of the process, as advertised by the company if commercialized. Known alternative names and second-party commercial aliases are also shown. *Year: The earliest known year of existence based on patents, reports of demonstrations, etc. The first public showing or commercial use (if any) may be later. *Projection method: a classification into one of four process types, plus a notation of how many primary colors were used:Additive: multiple black-and-white images photographed through color filters are projected through corresponding filters and united on ...

List Of Motion Picture 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 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 image projection. The format characteristics should be clearly definable in several listed parameters (e. g., film gauge, aspe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Monochrome And RGB Color Formats
This list of monochrome and RGB palettes includes generic repertoires of colors ( color palettes) to produce black-and-white and RGB color pictures by a computer's display hardware. RGB is the most common method to produce colors for displays; so these complete RGB color repertoires have every possible combination of R-G-B triplets within any given maximum number of levels per component. Each palette is represented by a series of color patches. When the number of colors is low, a 1-pixel-size version of the palette appears below it, for easily comparing relative palette sizes. Huge palettes are given directly in one-color-per-pixel color patches. For each unique palette, an image color test chart and sample image ( truecolor original follows) rendered with that palette (without dithering) are given. The test chart shows the full 256 levels of the red, green, and blue (RGB) primary colors and cyan, magenta, and yellow complementary colors, along with a full 256-level grayscale. G ...

Stereoscopy
Stereoscopy (also called stereoscopics, or stereo imaging) is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. The word ''stereoscopy'' derives . Any stereoscopic image is called a stereogram. Originally, stereogram referred to a pair of stereo images which could be viewed using a stereoscope. Most stereoscopic methods present a pair of two-dimensional images to the viewer. The left image is presented to the left eye and the right image is presented to the right eye. When viewed, the human brain perceives the images as a single 3D view, giving the viewer the perception of 3D depth. However, the 3D effect lacks proper focal depth, which gives rise to the Vergence-Accommodation Conflict. Stereoscopy is distinguished from other types of 3D displays that display an image in three full dimensions, allowing the observer to increase information about the 3-dimensional objects being displayed by head and eye mov ...

Anaglyph 3D
Anaglyph 3D is the stereoscopic 3D effect achieved by means of encoding each eye's image using filters of different (usually chromatically opposite) colors, typically red and cyan. Anaglyph 3D images contain two differently filtered colored images, one for each eye. When viewed through the "color-coded" "anaglyph glasses", each of the two images reaches the eye it's intended for, revealing an integrated stereoscopic image. The visual cortex of the brain fuses this into the perception of a three-dimensional scene or composition. Anaglyph images have seen a recent resurgence due to the presentation of images and video on the Web, Blu-ray Discs, CDs, and even in print. Low cost paper frames or plastic-framed glasses hold accurate color filters that typically, after 2002, make use of all 3 primary colors. The current norm is red and cyan, with red being used for the left channel. The cheaper filter material used in the monochromatic past dictated red and blue for convenience and ...

ColorCode 3-D
ColorCode 3-D is an anaglyph 3D stereoscopic viewing system deployed in the 2000s that uses amber and blue filters. It is intended to provide the perception of nearly full colour viewing with existing television, digital and print mediums. Danish company ColorCode 3-D ApS distributes the system. Technology One eye (left, amber filter) receives the cross-spectrum colour information and one eye (right, blue filter) sees a monochrome image designed to give the depth effect. The human brain ties both images together. Images viewed without filters will tend to exhibit light-blue and yellow horizontal fringing. The backwards compatible 2D viewing experience for viewers not wearing glasses is improved, generally being better than previous red and green anaglyph imaging systems, and further improved by the use of digital post-processing to minimise fringing. The displayed hues and intensity can be subtly adjusted to further improve the perceived 2D image, with problems only generally fou ...

The Toll Of The Sea
''The Toll of the Sea'' is a 1922 American silent drama film directed by Chester M. Franklin, produced by the Technicolor Motion Picture Corporation, released by Metro Pictures, and featuring Anna May Wong in her first leading role. The film was written by Frances Marion and directed by Chester M. Franklin (brother of director Sidney Franklin), with the lead roles played by Wong and Kenneth Harlan. The plot was a variation of the '' Madama Butterfly'' story, set in China instead of Japan. The film was the second Technicolor feature (after 1917's ''The Gulf Between''), the first color feature made in Hollywood, and the first Technicolor color feature anywhere that did not require a special projector to be used for screenings. The film premiered on November 26, 1922, at the Rialto Theatre in New York City, and went into general release on January 22, 1923. Plot When young Chinese woman Lotus Flower sees an unconscious man floating in the water at the seashore, she quickly get ...

CMYK Color Model
The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and is also used to describe the printing process itself. The abbreviation ''CMYK'' refers to the four ink plates used: cyan, magenta, yellow, and key (black). The CMYK model works by partially or entirely masking colors on a lighter, usually white, background. The ink reduces the light that would otherwise be reflected. Such a model is called ''subtractive'' because inks "subtract" the colors red, green and blue from white light. White light minus red leaves cyan, white light minus green leaves magenta, and white light minus blue leaves yellow. In additive color models, such as RGB, white is the "additive" combination of all primary colored lights, black is the absence of light. In the CMYK model, it is the opposite: white is the natural color of the paper or other background, black results from a full combination of colo ...
