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 colors of light depending on the temperature. Blue sky Natural light can be specified by color temperature reflecting to the color developed Rainy when carbon is burnt. The light of 3,200K (K=Kelvin, -273 °C equals Cloudy AWC to absolute zero temperature 0K) represents Partly cloudy the same value (color) as what develops when carbon is burnt at 3,200K (2,927 °C). Fine The relationship between the color temperature of the light source and weather Fluorescent lamp condition is indicated in the right figure. Let's study the difference of shooting an indoor object from shooting one outdoors. Studios Halogen lamp Tangsten lamp are usually lighted with incandescent lamps and the color temperature of a white object in a studio is around 3,000K. The color temperature of a white object outdoors is Candle 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. - 24 -
