There are no actual daylight light sources, only simulators. Constructing a practical light source that emulates a D-series illuminant is a difficult problem. The chromaticity can be replicated simply by taking a well known light source and applying filters, such as the Spectralight III, that used filtered incandescent lamps. [22]
[17] [18] While it uses standard P3 RGB primaries, the white point is D65 instead of the DCI ~6300 K white point. The D65 white point is the existing standard for common sRGB and devices (Adobe RGB also uses D65). Display P3 uses the sRGB transfer curve, which is approximately equivalent to a gamma of 2.2. [19]
ITU-R Recommendation BT.2020, more commonly known by the abbreviations Rec. 2020 or BT.2020, defines various aspects of ultra-high-definition television (UHDTV) with standard dynamic range (SDR) and wide color gamut (WCG), including picture resolutions, frame rates with progressive scan, bit depths, color primaries, RGB and luma-chroma color representations, chroma subsamplings, and an opto ...
D65 may refer to: Illuminant D65, a commonly used standard illuminant defined by the International Commission on Illumination; Greek destroyer Nearchos (D65)
The unique LPP light source technology introduced by Gigaphoton extends the lifetime of droplet generators by utilizing ultra-small Tin droplets on-demand, reducing downtime and cost. In addition ...
The Kruithof curve, with an example light source; D65 (Northern daylight), inside the pleasing region. [1]The Kruithof curve describes a region of illuminance levels and color temperatures that are often viewed as comfortable or pleasing to an observer.
Researchers use daylight as the benchmark to which to compare color rendering of electric lights. In 1948, daylight was described as the ideal source of illumination for good color rendering because "it (daylight) displays (1) a great variety of colors, (2) makes it easy to distinguish slight shades of color, and (3) the colors of objects around us obviously look natural".
