What does camera shake mean?

Camera jitter refers to the short-term jitter of the picture during camera shooting or video recording. This phenomenon is usually caused by the vibration, shaking or unstable support of the shooting equipment. In addition, jitter may also be caused by the photographer's hand shaking or moving rapidly. Camera shake will cause discomfort in visual experience, and even affect the viewing effect and content delivery.

Aiming at the problem of camera shake, there are many professional tools and technologies on the market to solve this problem. For example, using anti-shake algorithm in video recording can effectively reduce the jitter of the lens and achieve a more stable picture. In addition, in order to prevent non-professionals from shaking when holding the camera, there are many auxiliary devices, such as stabilizer, pan/tilt and stabilizer bar, which can improve the stability of shooting.

Camera shake can also have a good artistic effect in some cases. For example, when shooting moving scenes or fast-moving clips, proper shaking can create a higher-intensity picture effect, which will have a more vivid and shocking effect. At the same time, in shooting, the photographer will intentionally use jitter to reflect the emotional state of the characters and show the tension of the plot. In addition to technical means, the photographer's imagination and artistic sense are also the premise of creating artistic shock.
