White balance adjustment formula

The formula of white balance adjustment is that most scenes use automatic white balance of 70%, corresponding scenes use corresponding white balance of 20%, set manually if necessary, or adjust 10% after RAW.

White balance is to keep the balance of "white". In a broad sense, it refers to the standard of 18% middle gray level, so that the color of photos taken by the camera in different light environments can be restored to the standard "white" as much as possible. Simply put, it is the process of correcting the color cast of photos and restoring the "white" of the real world.

White balance is produced with the true color reproduction of electronic images, and it was applied earlier in professional photography. Many people will find that when shooting with a digital camera, the image taken in the fluorescent lamp room will appear green, the scenery taken in the indoor tungsten lamp will appear yellow, and the photos taken in the sunlight shadow will appear blue inexplicably, because of the setting of white balance.

Skills of using white balance

Photographers often take pictures of flowers. Don't use automatic white balance when shooting flowers, but adjust it according to the light source at that time. When shooting with a flash, the color temperature of the light emitted by the flash is basically the same as that of sunlight, so the white balance can be set to sunlight, even when shooting at night, which can better restore the color of the close-up scene.

When shooting the lake at sunset, if you use fluorescent white balance, it will make the picture warmer; If incandescent lamp mode is used, quiet blue color will be displayed, and warm color part can also be displayed. If you can't get a stronger color effect when shooting dusk with automatic white balance, you can use the blue target as the white reference point of the camera to "mislead" the white balance setting of the camera when customizing the white balance.
