On the black substrate of photography

Well, if you don't want that kind of high-gloss floor, I don't remember having a matt floor, so you usually use a background cloth. It's still very cheap to buy one meter.

If you do it yourself. . . Um ... It depends on what you shot. If you shoot jewelry, you can use velvet cloth, which will make the jewelry more dazzling under proper light. If it's non-jewelry, buy some black cardboard to make do, and the effect will be gone. . Still recommend the background cloth.
