Is it difficult to learn photography assistant ... How long does it take ...?

Half a year? Three months to learn? You know nothing about photography, do you? How long you can learn depends on yourself. Why did you start as a handyman? It's the photographer who is testing you. If it is a rotten piece of wood, it will be useless for three years. Even if you hang out with the top ten portrait photographers. You may not be a teacher in three months. You can work independently at most, but the real strength can only be tested in severe situations.

There is no end to learning. Even today's masters often watch other people's movies to learn from their experiences.

Don't lose heart. If you want to learn photography, you must first cultivate interest. If you just want to be a photography assistant, don't study photography. Everything is difficult at the beginning, and it will get better gradually.
