How to Adjust
_ White balance adjustment
Adjust the white balance after shooting a white object by at least 50% of the screen.
NOTE: If the white signal level is over 100% or less than 50%, the white balance may
not be normally adjusted.
_ Color temperature and while balance adjustment (reference)

the difference of shooting an indoorTangsten lamp

object from shooting one outdoors.
Studios are usually lighted with
2000K
incandescent lamps and the color
temperature of a white object in a studioCandle
is around 3,200K. The color temperature1000K
of a white object outdoors is aroundColor temperature values
6,500K. The former may look a little
yellowish while the latter appears
somewhat bluish when they are shot by a camera. However, the human eye does not
recognize color differences among these objects even under different ambient lighting
conditions, because of their adaptability to light.
The video camera reproduces color differences with high fidelity and the color of an
object somewhat different from what appears to the human eye.
Therefore, there is a need to adjust the white balance in order to correct differences
between color temperatures.
NOTE
Color temperature outdoors may vary depending on weather conditions.
