Can the photographer in the studio repair the film?

I have done post-processing in the studio before. That photo studio is not big either, but it is also an assembly line. Photographers only take pictures, and photography assistants are responsible for some lighting, scenery and so on. Photographers only teach customers how to pose, just press the shutter. However, this situation is common in smaller photo studios. In fact, you can leave this for a while to exercise, and when the technology is almost the same, you can go to a bigger photo studio. Because you have done all the work, you will be more competitive then.
