What is the film and television sports lens?

Film and television sports lens mainly refers to the movement of the lens itself, that is, the lens taken by sports photography. In film and television works, still pictures and shots are rarely seen. Let's take a closer look!

1. Push the lens:

A lens in which the camera moves slowly forward or quickly without changing the position of the subject. By pushing the lens, the visual range of the screen is from large to small, the secondary part of the screen is gradually pushed out of the screen, and the main part or local details are gradually enlarged to occupy the screen. In the scene, it has also changed from a distant view to a panoramic view, a middle view, a close view and even a close-up. The main function of this kind of lens is to highlight the subject, make the audience's visual attention relatively concentrated, strengthen the visual experience and create a state of scrutiny. It conforms to the visual psychology of people observing things from far and near, from whole to part, from panorama to detail in real life. For example, there is a scene in Citizen Kane, which keeps pushing the scene to the words just thrown into the stove sleigh: "Rosebud". The film highlights this detail, arousing great attention from the audience, and discusses the relationship between the protagonist and "Rosebud".

2. Pull the lens:

Contrary to the moving direction of the push lens, photography moves backward from being close to the subject to being far away from the subject; The range of framing changes from small to large, the subject changes from large to small, and the distance from the audience gradually increases. The image of the picture changes from less to more, from local to whole. In the scene, the close shot or the close shot and the middle shot are pulled into a panoramic view and a distant view. The main function of pulling the lens is to explain the environment in which the characters live.

3. Shake the lens:

The camera does not move, and the camera lens rotates up and down, left and right or even left and right with the help of the movable chassis, just like a person's eyes patrol the subject in a certain direction. Panning can represent the eyes of the characters and see everything around them. It plays a unique role in describing space and introducing environment. Swinging from side to side is usually used to introduce big scenes, while shaking up and down is usually used to show the grandeur and precipitousness of tall objects. When shaking the lens one by one and gradually expanding the scenery, it also makes the audience feel immersive.

4. Move the lens:

A lens in which the camera moves horizontally from one side to the other. Moving the lens means that the machine moves by itself without having to follow the subject. Similar to the state in which people walk and watch in life. Moving the lens can expand the two-dimensional space mapping ability of the screen like shaking the lens, but because the machine is not fixed, it has more freedom than shaking the lens. It can break the limitation of the picture, expand the spatial vision and show a broad life scene.

5. Follow the camera:

The camera moves at the same distance following the moving lens of the subject. The subject who follows the camera and always follows the movement has a particularly strong feeling of crossing the space, which is suitable for continuously expressing the movements, expressions or details of the characters. For example, a scene in Rashomon is in the mountains, occupying three-quarters of all the shots. In particular, the scene of robbers running in the bushes, the scene of creation and high-speed follow-up, and the quick jumping movements of characters on the hillside vividly depict the mountain thief as the most exciting part of the whole play by virtue of his strong martial arts and cunning and cruel nature.

6, lifting lens

The way that the camera takes pictures while lifting with the help of the lifting device is called lifting shooting, and the picture taken in this way is called lifting lens.

(1), the picture modeling characteristics of the lifting lens. First, the lifting movement of the lifting lens brings about the expansion and contraction of the picture field of vision. Secondly, the changing viewpoint of the lifting lens has formed a multi-angle and multi-directional multi-composition effect.

(2) The function and expressive force of the lifting lens. First, the lifting lens is beneficial to display all parts of tall objects. Second, the lifting lens is conducive to the expression of the point-surface relationship in deep space. Thirdly, the lifting lens is often used to express the scale, momentum and atmosphere of an event or scene. Fourthly, the content conversion and scheduling in the shot can be realized by using the promotion of the shot. Fifth, the lifting movement of the lifting lens can show the change of emotional state in the picture content.
