I have worked in a photo studio for thirteen years. The requirement for the later period is not how strong your PS is, but how capable you are and how much work you can do every day.

The main work in the later period is to design photo albums. The requirement is not how well you play PS, but whether you have those ideas.

You can say that you only know some operations, that is, the basics.

I suggest you ask a lower studio to find a teacher to shoot. It doesn't hurt to learn more.
