Why do many focal planes shake badly? Cann't it be avoided?

1. I suggest going to Nick Hospital, where the shaking is quite severe. Actually, it can't be called shaking. This is a style of image. France is known as the Doctrine 95 School. Recently, there is a research conclusion of image psychology, and sports shots make people pay more attention. Moreover, the film makes the lens more flexible through movement, and there are many internal scheduling. For example, Cici found the flyer lens of Jiang Chuanfa, which shows her skill and mind.

Non-professional camera shooting, that kind of low-cost movie, the money at continuous shooting circuit is not enough.

2. Deliberately create a documentary or documentary feeling, with a sense of substitution, such as death video, which is called mockumentary.

3. Deliberately create the effect of panic or confusion and anxiety. In order to increase the tension, that realistic style made the necessary obvious shaking. I mean, why do almost all movies have this unintentional slight shaking effect? Through careful observation, I found that all the movies I watched had stable shots produced by using fixed lenses and camera stabilizers and tracks.

4. In addition to the obvious lens shaking, which intentionally adds tension, there is always a lens effect that makes people feel slightly shaking intentionally or unintentionally. At this time, did the photographer deliberately shake the lens slightly behind the lens or did it come out in the later editing? What is the reason? You just want to push and pull the lens slowly. At the same time, why is there such an imperceptible shaking? Some of them are really slightly shaking, which makes people wonder and observe whether the lens is shaking or just the photographer is capturing the picture.
