Definition
The whitepoint is a color that is defined for each image as the normal “white”.
Depending on the light(s) illuminating the scene, the whitepoint can be different.
Typically, the whitepoint follows a line in the Color space that represents the colors emitted by a black body at different temperatures.
It is hence expressed as a temperature in Kelvin
Can whitepoints be outside of the black body colors ?
Why are some whitepoints blue when a black body cannot be blue ?
What is the green/magenta setting and is it related to the whitepoint ?
What is the whitepoint used for, other than changing it to adjust the "temperature" of an image ?
