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 white balance adjustment (reference)
When carbon is burnt, it develops various
Blue sky
colors of light depending on the temperature.
Natural light can be specified by color
Rainy
temperature reflecting to the color developed
when carbon is burnt.
Cloudy
AWC
The light of ,00K (K=Kelvin, –7 °C equals

to absolute zero temperature 0K) represents
the same value (color) as what develops

when carbon is burnt at ,00K (,97 °C).
The relationship between the color

temperature of the light source and weather
condition is indicated in the right figure. Let's
Halogen lamp
study the difference of shooting an indoor
Tangsten lamp
object from shooting one outdoors. Studios
are usually lighted with incandescent lamps
and the color temperature of a white object in
a studio is around ,000K. The color
Candle
temperature of a white object outdoors is
around 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.
