How to choose white balance in photography?

If there is a pure white object (such as a pure white wall) in the shooting scene, aim the lens at it to make it fill the camera viewfinder and adjust the manual white balance (different machines have different adjustment methods, please refer to the instruction manual, and generally press and hold the manual white balance button 1-2 seconds to complete the system prompt). See what happens to the screen (SLR digital cameras can't see the adjustment effect immediately)?

If there is no pure white object in the shooting scene, it is best to bring a piece of white paper to adjust the white balance, but it must be done in the light of the shooting scene. Of course, we can also use the principle of manual white balance to set the color cast effect we need. For example, aim the camera at a blue object (such as the blue sky), adjust the white balance and shoot the sunrise and sunset.

white balance

White balance literally means white balance. White balance is an index to describe the white accuracy of the mixed red, green and blue primary colors in the display. White balance is a very important concept in the field of TV camera shooting, through which a series of problems such as color restoration and tone processing can be solved.

White balance is produced with the true color reproduction of electronic images, and it was applied earlier in the field of professional photography. Nowadays, it is also widely used in household electronic products (home video cameras, digital cameras). However, the development of technology makes white balance adjustment easier and easier, but many users still don't understand the working principle of white balance, and there are many misunderstandings in understanding.

It is to realize that the camera image can accurately reflect the color condition of the subject, with manual white balance and automatic white balance. Many people will encounter such problems when shooting with a digital video camera: the images taken in a fluorescent lamp room will appear green, the scenery taken in an indoor tungsten lamp will appear yellow, and the photos taken in the shadow of the sun will appear blue inexplicably. The reason is the setting of white balance.
