There is no limit to the length of the scene in the camera, such as a panoramic view for a few seconds and a close-up for a few seconds.

Panoramic view 7-8 seconds, medium view 5-7 seconds, close view 2-3 seconds, close-up 1-2 seconds.

Scene difference means that the range of the subject in the camera recorder is different because of the different distance between the camera and the subject when the focal length is fixed. Generally speaking, there are five kinds of scenery, from near to far, namely: close shot (above the shoulders of human body), close shot (above the chest of human body), middle shot (above the knees of human body), panorama (the whole human body and surrounding environment) and prospect (the environment where the subject is located).

Content expression

As a single picture, Jingbie only expresses a visual form, and once they are arranged and combined with the content, they will inevitably play a vital role in the expression and performance of the drama content and narrative focus.

From the analysis of visual language and lens law, the more important the narrative content is, the more we should adopt a series of scenes such as middle shot and close shot. On the other hand, it adopts a series of visions and panoramas. Of course, this is a routine method for directors and photographers to handle shots for the main characters, and its starting point is mainly to design and use scenes for the actions of the characters. When designing films and structural vision, directors should consider the needs of narrative focus and drama content, which is reflected in the formation of visual expression-scene separation.
