How to solve the problems of inaccurate picture white balance setting and confusion of background picture color and light?

If you can't grasp the white balance at night in the early stage, it is recommended to shoot in RAW format. The advantage is that you can correct the problem of inaccurate white balance or get the desired tone later.

Different lighting will have an effect on the skin color of the characters. Generally, the color temperature of street lamps at night is around 2800-3200. If a flash is not used, try to adjust the color temperature of the camera to the same color temperature as the current ambient light. If you shoot with an external flash, you can weaken the output value of the flash, or add a soft cover to the light, try not to let the flash overshadow the ambient light, and only make some supplementary light for the characters. The best way is to use outdoor constant light with a color temperature of about 3000K and a soft light cover. Light is better than control. If the light is too bright, the background will darken and the ambient atmosphere will not stand out. The white balance of the picture is controlled by using led outdoor lights and flashlights.

Later LR and PS adjust the white balance. First of all, we must ensure that there is no exaggerated white balance problem in the early stage. For example, it is difficult to adjust later.
