Subject: Re: RAW and Kelvin Temp.



as you heat up a theoretical black body it changes color. It starts as black. As it increases in degrees Kelvin it glows reddish (dull red, then cherry red) and then moves towards yellow, then towards blue. As the temperature goes up it gets bluer until it eventually becomes white. It isn't how hot or cold you are, but the temperature of the light source (as compared to a black body radiator).

Zero degrees Kelvin is -273 degrees C. Higher temperature = cooler light.
