Colour temperature
Colour temperature is a measure for describing the colour of a particular set of light sources.
For a camera this colour temperature is a reference and all reproduced colours are derived
from this reference.
Auto white balance will give good performance in most cases but additional modes are
available for manually adapting in more difficult environments.
The table below gives the colour temperatures of some light sources as a general reference.
