Film is called the seventh art mainly because its appearance is closely related to what.

The film is called "the seventh art" mainly because its appearance is closely related to science and technology.

First, the orientation of film art.

Film art is the product of the combination of modern science and technology and art. Film art is the art of creating perceptual and intuitive images on the screen, reproducing and expressing life with pictures and sounds as the media.

Second, the expression technique

Montage is the most basic and unique artistic expression method of movies. The montage of movies includes not only the combination relationship between shots, but also the combination relationship between pictures and sounds, and between sounds, thus forming various organized fragments and scenes until a complete movie.

The world on the screen is a special space-time complex. Film is the crystallization of the collective wisdom of all kinds of artists, and the director is the center of film production. He must carry out comprehensive design and overall conception according to the script of film literature, fully mobilize the creativity of various arts and technologies, and jointly complete film creation.

Film shooting method:

1, depth of field lens

In optics, especially in video recording or photography, the depth of field (DOF) is a range of distances that can be clearly imaged in space. Depth of field is the range of good focus. It can highlight the subject by blurring the background, and can also shoot a clear background.

2, low-angle photography

Low-angle photography, a shooting technique, allows us to observe the world from different angles. Most of us look at the surrounding environment from the same angle in our life, and rarely put down our posture. But there is another world. Changing the angle can make the boring scenery fresh and vivid, as long as you pay attention to the correct method.

3. Micrographics

Microphotography is a method of shooting through a microscope. To obtain good microscopic effect, the most important thing is to have good microscope equipment and good microscope operation technology.

4, frame by frame photography

Frame-by-frame photography is one of the special shooting methods of focal plane. Use a frame-by-frame motor to drive the camera to shoot frame by frame. Finally, complete a complete shot. The screen effect is to greatly speed up the movement. For example, lotus flowers are in full bloom, dark clouds are rolling, sunrise and sunset, and buds are unearthed. It takes several seconds to show the actions that can be completed in a few days on the screen.
