Movies are the literature of portable sports. If you don't make the camera move, why do you let the audience not buy novels or watch the stage play, but pay for a movie theater that maintains a rigid posture for nearly 2 hours and has advertisements? "If you don't understand the movement of the movie camera, you can say that you can't watch movies, write scripts, make movies, and don't understand movies." - Zhou Chuanji In general TV series production, you don't spend a lot of energy on designing some Motion pictures are often just repeated cuts and simple actions to avoid visual monotony. In common American blockbusters, a very simple action often uses a large amount of camera movement to express its dynamism. For example, in the film "Infernal Affairs", it is just a shot of Matt Damon going up the steps. Shooting in motion, full of motion. (The film "Infernal Affairs 08:20) It is hard to imagine a movie without motion. If you want to make a more in-depth analysis of the moving picture, you must analyze it in more detail from the various factors of the scene (scene, depth of field). , angle, composition, scenery, lighting, positioning, etc.) Of course, another very important point is the expression of the meaning of the lens to the film. Movement is one of the basic characteristics of film, and it is also an important factor that distinguishes film from other art forms. Sports lens mainly refers to the movement of the lens itself, that is, the lens shot by the method of sports photography. In film and television works, it is rare to see footage in a static state. Plenty of shots are in motion. 1. Pushing the lens - when the position of the subject remains unchanged, the camera moves forward slowly or rapidly. By pushing the lens, the framing range of the screen is changed 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 fill the screen. In terms of scenery, it is also changed from long-range to full, medium, close-up or even close-up. The main function of this kind of lens is to highlight the subject, so that the audience's visual attention is relatively concentrated, and the visual experience is strengthened, resulting in a state of scrutiny. It is in line with people's visual psychology of observing things from far to near, from the whole to the part, from the whole to the details in real life. 2. Pull the lens - Opposite to the movement direction of the push lens, the photography moves away from the subject from near to far to the back; the viewing range 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 a local to a whole. In terms of scenery, the close-up or near and medium shots are drawn into panoramic and distant views. The main function of pulling the lens is to explain the environment in which the characters are located. 3. Panning - the camera does not move, but with the help of the movable chassis, the camera rotates up and down, left and right, and even around the camera, just like a human's eyes patrolling the subject in a certain direction. Panning can represent the eyes of the character, looking at everything around them. It has unique functions in describing space and introducing environment. Shaking left and right is often used to introduce big scenes, and shaking up and down is often used to show the majesty and steepness of tall objects. The panning also makes the audience feel immersed in the scene when it is displayed one by one and gradually expands the scene. 4. Shifting the lens - the camera is panned to the left and right along the horizontal direction to shoot the lens. Panning is when the machine moves on its own without having to follow the subject. It is similar to the state of people watching and walking in life. Like panning, panning can expand the screen's two-dimensional imaging capabilities, but because the machine is not fixed, it has more freedom than panning. It can break the limitations of the picture, expand the spatial vision, and express a wide range of life scenes. 5. Follow shot - a moving shot in which the camera follows the subject in an equidistant motion. The follow-up camera always follows the moving subject, which has a particularly strong feeling of passing through space, and is suitable for continuously expressing the changes of the characters' movements, expressions or details.
