What mode is used for white balance in auto show?

There are two custom white balance modes:

One: When shooting, take a piece of pure white paper (ordinary white paper is only nearly pure white, so you can find a kind of photographic equipment called "white card" on the market), use the "confession balance" of the camera, and then press the shutter on the white paper. The significance of this is to tell the camera what is "white" under this light source.

Two: Another way to customize the white balance is to directly assign the color temperature (K number) to the camera. After accurately telling the camera the color temperature, the camera can accurately calculate what is white and the corresponding other colors.

In fact, white balance means that different light sources have their relative color temperatures, so it is necessary to tell the camera exactly what the color temperature of the light source is when shooting, so that the camera can make an accurate interpretation of the color. In order to take good photos, we must not be sloppy in the white balance.

Some photographers deliberately use a white balance that doesn't match the ambient light to get a special tone, thus highlighting some themes. You can also try boldly in this direction. For example, if the white balance of the camera is set to be k higher than the color temperature of the ambient light source, a warmer/red tone can be obtained; Conversely, if the white balance is set to k number lower than the color temperature of the ambient light source, a cool/blue tone will be obtained. For example, under the scorching sun at noon, set the white balance in the "shadow" mode, and you will shoot warmer/redder tones; On the contrary, under the scorching sun at noon, set it as tungsten lamp, and you will get a cool/blue tone.
