Why do the scenes of some movies sway? Is it intentional?

In China, watching movies is a very common form of entertainment, and it is also a favorite sketch. Going to the cinema for a date is very emotional, which can not only enhance your feelings, but also better experience the movie. Nowadays, whether in our country or in TV series, the level of movies is getting higher and higher. Don't present more and more beautiful movies to the audience. Trying to make a good film has something to do with the shooting method of this film. In the movies we watch, the focal plane often hangs, and many people don't know the reason. It wasn't all intentional. 1 In order to create that kind of real atmosphere, the camera was deliberately shaken. The second situation is that some shots have to be taken with the camera, so they shake.

In the case of 1, the camera is shaking on purpose. Such scenes often appear in some suspense horror movies. Often you shoot from the first perspective of the protagonist. In order to make people feel real, the shaking lens also shows people's nervous sight, creating that kind of tense and exciting atmosphere.

In the second case, the camera shaking is not intentional, and they can't help it. Although there are machines for fixing cameras now, people have to follow the camera with their backs in order to shoot the camera in a narrow space. In this case, people's hands are unstable and they will see the lens shake. It may also represent another person's line of sight.

So this shooting technique does not affect the quality of the film.
