COLOR TEMP: Color temperature (technically measured in degrees kelvin) is a
measurement of the average wavelength of light being photographed.
Artificial lights (particularly older style tugnsten bulbs) have a low color temperature,
somewhere between 3000°K and 3500°K, and this appears to be an orange/yellow
color. The INDOOR setting will compensate for this, allowing the camera to more
accurately represent color, despite the yellow light.
Sunlight, on a clear day, has a higher color temperature (about 5600°K) and
appears slightly blue. The OUTDOOR setting will accurately represent colors under
these conditions.
BLUE/RED: You can make alterations to the color mix here. Changing these values
directly alters the mix of RED, GREEN and BLUE in your signal. The lower the
values, the less of these colors you will have and, of course, the inverse is true.
There is no direct way to control the amount of green in your signal - however, it
is easy to do. To increase the amount of green, decrease the amount of red and
blue. To decrease the amount of green, increase both the red and blue channels.
