How can the photos taken by photographers in the studio be called unqualified?

Only exposure and half-length shooting can be compensated. You can complain to the photographer. That photographer's skill is too poor. It's not good to rely only on post-photographers.

I don't know much about lighting either. I guess I haven't done it for a few days.

As for the background cloth and movie lights, it is normal, because the background cloth is something that the studio owner is reluctant to spend money on. These problems can also be adjusted later.

But the key is that photographers can avoid this kind of problem, can take telephoto, and avoid it completely.
