Why the background of the items I shot is very gray, and how to shoot the all-white background! Ask for advice ~ ~ ~

Why do you want to polish your products like this?

Tell you a way, so that the background won't be gray. Just add a bottom light on a white background.

There are brothers, there are many professional special lamps in the production area now, which are small and easy to use, and not very expensive. You search on Taobao, the product photo box, the others need to be assembled when shooting. I use the latter one, which is very transparent, textured and three-dimensional.
