What scenes are the camera's white balance "sunlight", "fluorescence" and "cloudy" suitable for? What are the values ??of Kelvin?

The camera's white balance and set color temperature refer to the color of light emitted by various light sources. It uses the color emitted by iron at various high temperatures as a standard reference value.

Daylight: Take pictures of sunlight on a sunny day, the color temperature is about 5400K. In other words, when iron is at a high temperature of 5,400 degrees, its color is consistent with the color of sunlight on a clear day. The same applies below.

Fluorescence: Shooting in an environment illuminated by fluorescent lights. The color temperature of fluorescent lights is difficult to determine, and can be divided into warm colors and cold colors. Warm fluorescent lights are mostly 3500K, and cool fluorescent lights are mostly 4500K. The color temperature is different from the material of the lamp. There is a difference.

Cloudy: refers to shooting in a cloudy environment with no sunlight, and the color temperature is 6000K.

So, when shooting, you must correctly set the color temperature of various lights for shooting. If the color temperature of the light is not accurate, use automatic mode. Otherwise, the light color temperature setting of the white balance will not be accurate. Correct, the photos taken will have a color cast.
