Be sure to know the color temperature and white balance.

What is color temperature?

Color temperature refers to the color of light produced when a blackbody is heated to a certain temperature, which is called the color temperature at this temperature.

Variation law of color temperature k value

The smaller the k value, the lower the color temperature, the yellowish color tone, and the warmth and tranquility. The greater the k value, the higher the color temperature, the bluer the color tone, and the cold and sad.

What is white balance?

White balance literally means white balance. No matter what light source, white objects can be restored to white. The unit of white balance is also k, and the white balance is represented by AWB in the camera.

Variation law of white balance k value

The smaller the k value, the bluer the hue. The greater the value of k, the lower the color temperature of yellow.

Relationship between color temperature and white balance

Conceptually, color temperature and white balance are completely different concepts. White balance is derived by the photographer to express the light problem in photography, but because the adjustment process of white balance is through color temperature, the color temperature is a white balance problem relative to the camera.

From the change law, the change law of color temperature and white balance is completely opposite. The greater the color temperature, the colder the photo (blue), and the smaller the white balance, the colder the photo.

How to use white balance

If you want to take a warm (yellowish) photo, improve the white balance K value.

If you want to take a cool (blue) photo, lower the white balance K value.

How to set white balance

Automatic white balance

That is, the camera automatically adjusts the white balance according to the ambient light source, which is suitable for use in a single light source environment.

Manual white balance

In the case of complex light source, you need to manually set the white balance, select the preset white balance mode, or manually adjust the white balance K value to the color you want.
