What is the essential difference between hand-held photography and unstable camera in movies?

Hand-held photography has great flexibility and convenience, which is the biggest feature compared with fixed position photography. It is "unstable" and can quickly capture the "accident" in the shooting process. When the photographer walks, breathes or chases, the camera screen will shake or shake to some extent. The photographer's mood, action range and rhythm determine the degree of jitter of the picture, which can fit the real situation of the film content.

Especially when time is tight and space terrain is limited, the flexibility of hand-held photography appears when fixed tripod camera and moving track cannot be realized. From the perspective of mobility, its shooting method comes from documentary, which is to effectively capture fleeting images. Photographers must have keen eyes, because all ideas are expressed through the focal plane. He cooperated with the director to complete the picture and naturally became the soul of film creation. His hand-held shooting skills and experience directly affect the quality and level of the film to some extent.

Hand-held photography is "subjective" and conscious, as a form of photography. An artistic language. The instability of holding the camera is objective and passive, that is, you obviously want to take a calm photo, but because of the instability of holding the camera, you took a dynamic and blurred photo. Holding hands can show some emotions, make the audience feel nervous and afraid of strangeness, or show bumps and urgency in some chase scenes, from which the audience can get information, while shaking hands when shooting video can neither get the information in the picture nor feel the atmosphere. Or the normal picture suddenly bumps up and down, and the character drawing is meaningless.
