What is reference white?
A white point (often referred to as reference white or target white in technical documents) is a set of tristimulus values or chromaticity coordinates that serve to define the color “white” in image capture, encoding, or reproduction.
What is a chromaticity coordinate?
Chromaticity coordinates are the best estimate of color gamut and LED suitability for a particular display since color differences will be noticeable between two neighboring modules.
What is the CIE chromaticity diagram for?
The chromaticity diagram illustrates a number of interesting properties of the CIE XYZ color space: The diagram represents all of the chromaticities visible to the average person. These are shown in color and this region is called the gamut of human vision.
What white balance should I use?
The Best White Balance for Landscape Photography
- Kelvin 3200-4000 is ideal for most types of night photography, whether you’re photographing the Milky Way or the Northern Lights.
- Kelvin 5000-6000 is ideal for most types of ‘regular’ landscape or outdoor photography.
What is chromatic purity?
Colorimetric purity (pc) represents the ratio of chromatic luminance to total luminance of a color stimulus [Eq. (1) below].
Where do we find white colour in chromaticity diagram?
The white lies on the central point ‘C’ with coordinates x = 0.31 and y = 0.32. Actually there is no specific white light—sunlight, skylight, daylight are all forms of white light.
Can white balance affect overexposure?
White Balance can affect the Exposure if you shoot in RAW. If you are photographing a scene with a very wide dynamic range, changing one of the color channels may affect the exposure. One of the overexposed color channels may be clipping. This is the only example of the effect of the White Balance on the Exposure.

What do you mean by white light?
This contains all the wavelengths of the visible spectrum at equal intensity. In simple terms, electromagnetic radiation of all the frequencies in the visible range of the spectrum, appearing white to the eye is called white light. Visible light or white light comes above infrared rays.
What is a visible light?
Visible light or white light is the part of the electromagnetic spectrum that can be detected by the human eye. Visible light and it’s immediate near-infrared light is typically absorbed and emitted by electrons in atoms & molecules that move from one energy level to another.
What is white light in Reiki?
Phylameana lila Desy, the author of “The Everything Guide to Reiki,” is a freelance writer, holistic healing consultant, intuitive counselor, and an energy medicine practitioner. White light is the space within the universe that houses positive energies.
What is the color temperature of a white light source?
White light sources and their corresponding illuminants usually have correlated color temperature (K) and color-rendering index (CRI) values associated with them. White light sources vary from warm white to cool (blue) white.
