Is the screen wall 8m long enough?

That's enough. Shadowless walls are mostly used in large cinemas because there is no background paper more than 3 meters wide.

The production of shadowless wall is relatively simple, and the cement floor needs to be painted with white latex paint with radian in the middle. Shadowless walls are generally large studios with large areas and wide uses.

There is an arc-shaped white wall in the studio, commonly known as the thing-shadowless wall. Shadowless walls are not made without shadows. The special purpose of this arc wall is to present the shadow of the subject more naturally, and the shadow is integrated. The place where the shadowless wall extends to the ground in the photo studio is made of PVC floor material, which is more common.
