The background wall (white wall) of the studio is curved where it meets the ground. What material is it made of? What kind of paint is used?

Seamless wall can't be done in a narrow space.

It itself is used in greenhouses.

The keel behind the wall is inclined, not vertical. The wall can be fixed on the keel with plates, and the corner is an arc with a diameter of 3 meters, and there can be no dead angle shadow.

Paint can't be paint, only wall paint. If it is dirty, you can repaint it or knock it off with draft paper.

You should clean the shoes you want to step on first, and you can clean them once a year and a half.
