The problem of shooting angle, the definition and characteristics of back angle ~ ~ ~ urgent ~ ~

1. The shooting angle of Ping She camera and subject at the same horizontal line. Ping She can be generally divided into front, side and inclined plane. Frontal shooting, the optical axis of the lens is consistent with the apparent horizon (or center point) of the object, which constitutes frontal shooting. The advantages of the front lens are: the picture looks dignified and the composition is symmetrical. Used to shoot magnificent buildings and give people a panoramic view; Shooting people can truly reflect the positive image of people. Its disadvantage is poor stereoscopic impression, so scene scheduling is often used to increase the depth of the picture. Side shooting, shooting from the direction at right angles to the apparent horizon of the object, is called side shooting. The side shot is divided into left and right sides. The characteristics of side shot are helpful to outline the outline of the object. Oblique, the shooting angle between the front and the side is oblique. Oblique shooting can show both sides of an object in one picture at the same time, giving people a distinct three-dimensional sense. Oblique shooting is the most common shooting angle in film and television teaching materials. 2. The upward camera shoots from a lower position to a higher position. Upward photography is suitable for shooting high-altitude scenery, which can make the scenery look more tall and majestic. Use it to represent the line of sight of film and television characters, and sometimes to represent the high and low positions between objects. Because of perspective, the horizontal line in the picture is lowered, the contrast between the objects in the foreground and the background is changed, and the objects in the foreground are highlighted and exaggerated, thus obtaining special artistic effects. In film and television teaching materials, shots are often used to express people's praise for heroes or awe of certain objects. The elevation angle is approximately vertical, which is called large elevation angle. Generally, it represents the point of view of the character to express his mental state such as dizziness and fainting. Contrary to aerial photography, the camera shoots down from a height, giving people a feeling of overlooking. The overhead lens has a wide field of vision and is unique in the broad scene. Shooting from a high angle, the horizontal line in the picture rises, and the surrounding environment is fully expressed, while the objects in the foreground are projected on the background, giving people the feeling that they are close to the ground and become short and depressed. It is very common to show the hateful smallness of the villain or the despicable behavior of the character with the overhead lens. 4. The shooting direction of overhead camera is perpendicular to the ground. It is unique to shoot some acrobatic programs or song and dance performances with the top corner. It can make some expressive shapes into exquisite pictures from an angle that one can't reach at all. The function of aerial photography is that it changes the normal state of the subject, changes the spatial position of people and environment into a plane pattern with clear lines, and thus makes the picture interesting and aesthetic. The head angle is rare in film and television. 5. When the film in the reverse film camera passes through the film gate, it runs in the opposite direction to shoot. In this way, the motion process of the photographed object can be projected forward, and the effect opposite to the actual motion direction can be obtained. Reverse photography is often used to shoot thrilling scenes. In TV shooting, the reverse shooting method is also commonly used. 6. Lateral reflex shooting is shooting from the back of the subject, which is called lateral reflex shooting. In this way, the figure almost becomes the back, and the face presents less, which can produce a wonderful feeling.
