WB is a Canon SLR camera, but what's the use?
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 professional photography.
White balance is to realize that the camera image can accurately reflect the color condition of the subject, including manual white balance and automatic white balance. Many people will encounter such problems when shooting with digital video cameras: the images taken in the fluorescent lamp room will be green, the scenery taken in the indoor tungsten lamp will be yellow, and the photos taken in the sunlight shadow will be blue inexplicably. The reason is the setting of white balance.
Extended data:
The public's understanding of white is brightness without color components. White or other colors seen by human eyes are related to the inherent color of the object itself, the color temperature of the light source, the reflection or transmission characteristics of the object, the visual perception of human eyes and many other factors. For a simple example, when colored light irradiates an achromatic object, the color of the reflected light of the object is the same as that of the incident light, that is, the white object is red under white light irradiation. When more than two colored lights irradiate the achromatic object at the same time, the color of the object shows additive effect, such as red light and green light irradiating the white object at the same time. When colored light shines on a colored object, the color of the object decreases.
