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)

When carbon is burnt, it develops	10000K
various colors of light depending on the		Blue sky
temperature. Natural light can be	9000K
specified by color temperature reflecting		Rainy
to the color developed when carbon is	8000K	Cloudy
burnt.
The light of 3,200K (K=Kelvin, –273°C		AWC
	7000K	Partly cloudy
equals to absolute zero temperature 0K)
represents the same value (color) as	6000K	Fine
what develops when carbon is burnt at
3,200K (2,927°C). The relationship	5000K	Fluorescent lamp
between the color temperature of the
light source and weather condition is	4000K	Halogen lamp
indicated in the right figure. Let’s study
the difference of shooting an indoor	3000K	Tangsten lamp
object from shooting one outdoors.
Studios are usually lighted with	2000K
incandescent lamps and the color
temperature of a white object in a studio	1000K	Candle
is around 3,200K. The color temperature
of a white object outdoors is around		Color 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.
