If it's photography, go out on location to help the master get things, help the couple pose, and then learn from the master. . .
If you are a post-assistant, you are always looking at the computer and fixing photos. Of course, you still have to watch the master do it first, and then learn slowly by yourself.
The salary is generally not high, 800- 1500, and assistants are like this. People will say that you come to study and confiscate your money.
So don't go in as an assistant if you can. Otherwise you will be very tired. Unless you are determined to do photography, you can start your assistant career in half a year, and then you will have a lot of money.
