When taking ID photos, the red color in the background will be reflected on people's faces. How to solve this problem?

I guess you are glowing. If it really doesn't work, you can take pictures with a white background and then change the background color. You can use the permission star, click' background processing' in the toolbar, and click the background color you need to replace in the color area below the background replacement box. Click on the bottom background color, or you can customize the background color.
