Can you tell me how the color temperature changes and how to adjust it when shooting?

The color temperature of sunlight is not fixed in a day, but changes regularly with time. It's low in the morning and evening and high at noon. The average color temperature of sunlight is 5600K, and artificial light sources also have different color temperature indicators. When developing positive films, the chromatic aberration of film photography caused by the change of color temperature from day to day can be corrected by light distribution. In TV camera shooting, it is mainly solved by adjusting the balance between black and white. Specific methods of adjusting the balance between black and white (omitted). Outdoor natural light and indoor natural light are high color temperature light around 5600K, and indoor light is mainly skylight, which is higher than the color temperature of sunlight. The color temperature of indoor natural light has nothing to do with the lighting quality.

On sunny days, the direct sunlight time is between 9- 15 hours, and the proportion of red, green and blue in sunlight is basically the same, each accounting for 1/3. So it gives people a white feeling. Tungsten lamp and civil light bulbs have low color temperature. Among them, there are more red components, giving people a reddish feeling. Fluorescent lamps contain more blue-green components. Give people a feeling of turquoise.

The color temperature of the lamp changes with the voltage. When the voltage is high, the color temperature is high, and when the voltage is low, the color temperature side is low. The approximate number of the standard voltage is 220V V, and the low voltage of 3-2V has little effect, so the human eye will not notice it.
