CHAPTER 33 Color Temperature
Color temperature is a physics concept. The color temperature of any point in the spectrum is that temperature in degrees Kelvin (Celsius scale with zero as absolute zero) to which a black body (what's that, you ask? don't worry about it) must be heated to produce that color (wavelength). It's nice to know this, but the physics of it has no practical application in cinematography.
We must know about color temperature, however, since film does not respond to light the same way eyes do. It's the same way for electronic imagers (CCDs, CMOS, and whatever is new in the last month). Your eye-brain system “knows” what the color of most objects is supposed to be. The processing of nerve impulses in the brain from the optic ...
