White balance setting in SLR camera: What is the color temperature of automatic sunlight shadow, fluorescent lamp, fluorescent lamp and incandescent lamp on cloudy days?

The white balance of the camera, that is, the set color temperature, refers to the color of the light emitted by various light sources. It takes the color emitted by iron at various high temperatures as the standard reference value.

Daylight: Take a sunny photo with a color temperature of about 5400K K ... That is to say, at a high temperature of 5400 degrees, the color of iron is the same as that of sunlight. The same is true below.

Fluorescence: It is difficult to determine the color temperature of fluorescent lamps when shooting in an environment with fluorescent lighting, which can be divided into warm colors and cold colors. Warm fluorescent lamps are mostly 3500K, and cool colors are mostly 4500K K. The color temperature is different from the material of lamps.

Cloudy day: refers to the shooting ability of cloudy day without sunshine, with a color temperature of 6000K K k.

Influence of color temperature of light source on color tone of picture

The color temperature of light source can be roughly divided into three grades: low color temperature, medium color temperature and high color temperature. 2 1 13

Low color temperature: the color temperature is below 3300K, and the reddish color gives a warm feeling of 526 1; Have a stable atmosphere and warm feeling of 4 102; When a light source with low color temperature is used, red can be more vivid.

Mid-color temperature: the color temperature is in the middle of 3000-6000 K, and people have no obvious visual psychological effect in this color tone. 1653 has a refreshing feeling; So it is called "neutral" color temperature. When the neutral temperature light source is used for lighting, blue has a cool feeling.

High color temperature: the color temperature exceeds 6000K, and the light color is blue, giving people a cold feeling. When using a high color temperature light source, the object feels cold.
