Using white balance to turn noon into early morning

Interested friends may notice a phenomenon, that is, the photographer will inexplicably aim the camera at the white clouds in the sky or the surrounding white objects, and then start taking pictures after some debugging on the camera.

At this time, we not only have doubts: what is the photographer doing? The answer is that they are adjusting the white balance, images of white objects (white clouds, whiteboards, etc. ) is restored, so they appear as white in the camera palette, as shown below:

What is white balance?

White balance means that no matter under any light source, photographic equipment can restore white objects to white (under different lighting conditions, adjust the proportion of the three primary colors of red, green and blue to mix them into white).

Generally speaking, it is to make white objects in the actual environment also appear in the shooting picture? Really? White.

Why should I adjust the white balance?

White balance is used to correct color shift, because white objects in reality are sometimes not white in the camera. Because people's eyes can correctly identify colors, no matter how the color of the environment changes, our visual system will automatically compensate for different lights, so that the white paper we see will always be white.

But photographic equipment will produce different color tendencies under different light sources. For example, if we take photos with our mobile phones, the images in the fluorescent room will be green, the scenery in tungsten lamp will be yellow, the photos taken in the shadow of sunlight will be blue, and the white paper will be red by candlelight.

At this time, adjusting the white balance is to make the white paper appear white in the camera in candlelight environment, so that when taking pictures in candlelight environment, all the objects can be guaranteed to be the original colors.

White balance is very important for taking photos with mobile phones. Similarly, the white balance debugging level of13 megapixel camera directly affects the photographing effect (Apple has accumulated rich technology in white balance debugging, so it also uses an 8 megapixel camera, which is better than most mobile phones).

Generally speaking, the automatic white balance mode in mobile phone photography can be automatically adjusted to the required lighting environment (incandescent lamp, sunlight, fluorescence, cloudy day), but the manual mode can be used well to take better photos.

How to take creative photos with white balance?

Through adjustment, you can also create different styles of photos. For example, you can use cloudy mode indoors to make the picture warm and yellow, and make the work warm and natural; Tungsten lamp mode can also be used to create a cold atmosphere. As long as it can be freely changed according to the subject matter, it is equivalent to adding a layer of filter effect to the photo.
