Advantages and disadvantages of fixed lens and moving lens in artistic expression

The difference between a fixed lens and a moving lens is: different viewpoints, different fluency and different composition changes. 1. Different viewpoints 1, fixed lens: The fixed lens has a single viewpoint, and the viewing area is limited by the frame of the picture. 2. Action shot: The action shot has a comprehensive viewpoint, and the viewing area is not limited by the frame of the picture. Second, the fluency is different. 1, fixed lens: fixed lens is easy to cause a sense of fragmentation, and it is difficult to completely and truly record and reproduce the original appearance of life. 2. Action shooting: Action shooting is smooth, and the picture can completely and truly record and reproduce the original appearance of life. Third, the composition changes differently. 1. fixed lens: the modeling elements in the frame with fixed lens are relatively concentrated and stable, and it is difficult for a lens to change the composition. 2. Action shot: The modeling elements in the action shot are completely tiled. With the change of shooting angle, one shot can realize composition. But in the process of shooting a lens, the camera position, lens optical axis and focal length are fixed, and the shooting object can be static or dynamic. Fixed lens is a static modeling method, the core of which is that the frame attached to the screen is not moving, but it is not completely equivalent to art works and photographic photos. The characters in the picture can move freely, draw a picture, and the light and shadow of the same picture can also change. Advantages: 1, fixed lens is beneficial to performance in static environment. In the editing of event news such as meeting place, celebration and accident, fixed the picture is often used to explain the place and environment of the event with a long-term vision and panorama. 2. The fixed lens can objectively record and reflect the movement speed and rhythm changes of the subject. Because the camera follows the moving subject and the background flashes by, it is difficult for the audience to compare it with some reference objects.
