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. | AWC Cloudy | |
The light of 3,200K (K=Kelvin, | Partly cloudy | |
to absolute zero temperature 0K) represents | ||
the same value (color) as what develops |
| |
when carbon is burnt at 3,200K (2,927 °C). | Fine | |
The relationship between the color | Fluorescent lamp | |
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 3,000K. 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.
