LasVegas’ Sphere and the Big Sky Camera
https://theasc.com/articles/sphere-and-the-big-sky-camera
Sphere is a 516′-wide, 366′-tall geodesic dome that houses the world’s highest-resolution screen: a 160,000-square-foot LED wraparound that fills the peripheral vision for 17,600 spectators (20,000 if standing-room areas are included). The curved screen is a 9mm-pixel-pitch, sonically transparent surface of LED panels with 500-nit brightness that produce a high-dynamic-range experience. The audience sits 160′ to 400′ from the screen in theatrical seating, and the screen provides a 155-degree diagonal field of view and a more-than-140-degree vertical field of view.
The image on the screen is 16K (16,384×16,384) driven by 25 synchronized 4K video servers.

Photography basics: Color Temperature and White Balance
Color Temperature of a light source describes the spectrum of light which is radiated from a theoretical “blackbody” (an ideal physical body that absorbs all radiation and incident light – neither reflecting it nor allowing it to pass through) with a given surface temperature.
https://en.wikipedia.org/wiki/Color_temperature
Or. Most simply it is a method of describing the color characteristics of light through a numerical value that corresponds to the color emitted by a light source, measured in degrees of Kelvin (K) on a scale from 1,000 to 10,000.
More accurately. The color temperature of a light source is the temperature of an ideal backbody that radiates light of comparable hue to that of the light source.
