Anyone who has photographed small things with the film board as the photographic background, please upload the works, thank you!

Do you want a reflective surface or a dull white background?

White cardboard

Nonwoven fabric:

There are many reflective surfaces and matte surfaces on the internet. Find it yourself.

Pay attention to the brightness of the background, otherwise it will be difficult to pull it out.

What kind of effect do you want? Can you be specific? In fact, it's all the same. As long as the background is bright enough, it will turn white.
