Colour / color saturation Explanation: Colour / color saturation is the right translation as mpm6 suggested. Your camera apparently offers relatively natural colo(u)rs except that the reds are somewhat over-saturated. What you do with the AE-BE spelling depends on your readership. "color saturation" draws 6053 AV hits and "colour separation" draws 1286 hits. Colo(u)r saturation refers to the absence of white (or the opposite colo(u)r if you are referring to a paper print) in the colo(u)rs in your image. If the green in your image looks grayish (German technicians say "schmutzig" – caused by the presence of the opposite colo(u)r – magenta – in the green) or whitish (wishy-washy, too much white light in the green) then the colo(u)r saturation is low. A 100% saturated digital color does not contain any white; adding white reduces saturation. There can be many reasons for poor colo(u)r saturation, but one is a cheap lens because a cheap lens throws some of the incoming light all over the image area, thereby distorting all the colo(u)rs in the scene. Colo(u)r saturation is often referred to as "chrominance" in TV and videospeak, but actually "chrominance" includes colo(u)r saturation and colo(u)r hue. Here are some sites with some definitions and references concerning lens design, cameras, video and TV with regard to colo(u)r saturation: http://www.yanman.com/HomeTheater/HTGlossary.htm#sectC "Chroma-Differential Gain: In video, a measure of how color saturation varies with scene brightness. Chroma-Differential Phase: In video, a measure of how color hue varies with scene brightness. Chroma Level: In video, a measure of color saturation. Chroma Phase: In video, a measure of color hue, usually adjustable with the tint control on a TV set. Chrominance: The color component of a modern television signal." http://www.videoessentials.com/glossary.htm#C "Chroma: The characteristics of color information, independent of luminance intensity. Hue and saturation are qualities of chroma. Black, gray, and white objects do not have chroma characteristics. Chrominance: The amount of color; or the saturation of color, in a picture. Saturation: The intensity of the color is called saturation. It is the distance away from the "black body curve" on the CIE diagram. Color saturation on a display device is controlled by the Color control. Apparent saturation of colors in a picture can be effected by the luminance value of the signal. Color saturation is measured on a vectorscope by the distance away from the center of the scope display." http://www.camera-collectors.com/store/rodenstock.html "They are extremely sharp, have strong color saturation with accurate color rendition, and demonstrate great contrast." http://www.cs.columbia.edu/~hgs/rtp/glossary.htm#c "Chrominance: That portion of the video signal which contains the color information (hue and saturation). Video picture information contains two components: luminance (brightness and contrast) and chrominance (hue and saturation)." http://www.cohu.com/cctv/glossary.htm Color Saturation: The degree to which a color is free of white light." Many digital cameras offer a "saturation" feature that works like the saturation smudge function in programs like Photoshop; more of the predominant colo(u)r is artificially added to the "real" or "natural" colo(u)r. This is similar to the old trick of using a Polaroid filter to get a bluer blue sky. This feature is discussed below: http://216.110.36.24/NEW1.HTM "In our tests, we were impressed with its accurate color, and liked the fact that you could choose between the subtly boosted color saturation of its "saturated" color mode, or the more accurate "neutral" option. Rather than the often wildly saturated colors produced by other cameras we've seen that have a "saturated" color mode on them, the variations between the DC4800's saturated and neutral options are more like the variations between different emulsions in the film-based world." HTH - Dan |

saturation Explanation: In the 1800's, Grassmann showed that 3 coordinates could specify colour. Since colour is used for computer screens and other commercially interesting objects, much has been done recently. The URL that follows explains a commonly used colour theory: hue, saturation, and intensity are the 3 quantities that determine the colour. This URL identifies saturation with Farbsättigung. I know this is right because I am familiar with the DIN documents on colour. Best wishes, Nancy Reference: http://www.informatik.fh-muenchen.de:2002/german/level004/ht... |
