Both of the cited standards specify a 6500 K color temperature. Most video and digital still cameras can adjust for color temperature by zooming into a white or neutral colored object and setting the manual "white balance" (telling the camera that "this object is white"); the camera then shows true white as white and adjusts all the other ...
Color correction is a process used in stage lighting, photography, television, cinematography, and other disciplines, which uses color gels, or filters, to alter the overall color of the light. Typically the light color is measured on a scale known as color temperature, as well as along a green – magenta axis orthogonal to the color ...
Infrared thermography ( IRT ), thermal video and/or thermal imaging, is a process where a thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process, which are examples of infrared imaging science. Thermographic cameras usually detect radiation in the long- infrared range of the ...
A color rendering index ( CRI) is a quantitative measure of the ability of a light source to reveal the colors of various objects faithfully in comparison with a natural or standard light source. Color rendering, as defined by the International Commission on Illumination (CIE), is the effect of an illuminant on the color appearance of objects ...
Gamma correction is a type of power law function whose exponent is the Greek letter gamma ( γ ). It should not be confused with the mathematical Gamma function. The lower case gamma, γ, is a parameter of the former; the upper case letter, Γ, is the name of (and symbol used for) the latter (as in Γ ( x )).
With professional video cameras, color temperature adjustments are made to achieve the same effect. With digital post production now nearly universal, the color temperature adjustment is usually made in camera, to preserve the "white" artificial lights, but scene darkening is left to post production for finer control of the effect.
Video demonstration of high-speed flash photography. A flash is a device used in photography that produces a brief burst of light (typically lasting 1⁄1000 to 1⁄200 of a second) at a color temperature of about 5,500 K (5,230 °C; 9,440 °F) [ 1 ][citation needed] to help illuminate a scene.
The aim of color calibration is to measure and/or adjust the color response of a device (input or output) to a known state. [ 1] In International Color Consortium (ICC) terms, this is the basis for an additional color characterization of the device and later profiling. [ 2] In non-ICC workflows, calibration sometimes refers to establishing a ...
