How long does it take to reach the level of a studio photographer?

Questions:

1: How long does it take to reach that level with hard work: It depends on your understanding, it can be as fast as 2 months or as slow as half a year. If it exceeds half a year, give up, it’s not that material.

2: How long does it take to be transferred to a formal photographer: if the level is sufficient, it will take half a year. If you are not transferred, you will directly change jobs.

3: If you reach that level but this photo studio does not allow you to become a regular employee soon, how about applying for a job as a photographer in another photo studio: you can change jobs, or you can open your own one.
