How to work in a photography studio or studio?

The studio must have relevant work experience. You have theoretical foundation and work experience. It should be no problem to apply for a photography assistant, mainly because you are diligent and have an eye. I have been a photographer for two years. I won't let an impetuous lazy assistant touch the camera. So if you have a good relationship with the photographer, you will have the opportunity to practice. If you have good personal understanding, you will make rapid progress.

I hope you will succeed soon.
