Is the drone lens moving, pushing or moving?

Movies are literature of portable sports. If you don't let the camera move, why do you ask the audience not to buy novels or watch stage plays, but to spend money on a cinema with advertisements and rigid posture for nearly two hours? "If you don't know sports in the focus plane, you can say that you can't watch movies, write scripts, make movies or understand movies." -Zhou Chuanji Generally speaking, in the production of TV series, we don't spend a lot of energy to design some moving pictures. We often just cut the lens repeatedly and use some simple actions repeatedly to avoid visual monotony. In common American blockbusters, a very simple action often uses large-scale lens movement to express its movement. For example, in the movie Infernal Affairs, it is just the shot of Matt Damon going up the steps, which is full of movement through the movement of the elevator. (The movie Infernal Affairs 08:20) It's hard to imagine a movie without action. If we want to make a more in-depth analysis of moving pictures, we should make a detailed analysis of various factors of scene scheduling (scene, depth of field, angle, composition, scenery, light, position, etc.). Of course, it is extremely important for the lens to express the meaning of the film. Sports is one of the basic characteristics of movies, and it is also an important factor that distinguishes movies from other art forms. 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. Many touching scenes. 1. Push lens-A lens in which the camera moves slowly or quickly when the position of the subject remains unchanged. 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. 2. Pull the lens-opposite to the movement direction of pushing the lens, photography retreats from near and far to 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 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 has a unique function 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. Moving lens-the lens in which the camera moves horizontally from left to right. 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-up lens-a moving lens, and the camera keeps moving equidistantly from the main body. 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.
