There are three kinds of cameramen: news topic cameraman, film cameraman and wedding cameraman.
If you want to be a "conference wedding photographer", the simplest mode is to buy a video camera and shoot it. After several years of shooting, you will gradually have a good level. If you want to hurry, you can worship a master. If you want to join the business in a month or two, you can only attend training.
If you want to be a "news topic cameraman", if you have no foundation at all, you can only attend training.
This industry doesn't need Ding Bai to recruit assistants.
If you want to be a "video cameraman", you should attend the training first, and then find an opportunity (now you can find it) to join the crew. This is the hardest.
For information about the position and professional skills of cameraman, please refer to my Baidu space.
A lot of information about this.
