What color is the "solid color" of the background cloth commonly used in photo studios?

Personal views should still have a white background and be highly malleable. It's easy to deduct pictures with ps. I think so on the issue of real scene and ps synthesis. If your customers are demanding and the labor cost is sufficient, you can choose to shoot the real scene outdoors, which will not only have a good shooting effect, but also spray the name of your studio on your reflective umbrella, photo box and other equipment for advertising. It's a waste of effort. Why not? If it's an ordinary small customer, forget a few hundred dollars. The cost is too high to cover the travel expenses. Just choose the late ps. The effect is also good, and many studios that are not very big basically choose this. Personal opinion, for reference only.
