Light and shadow directly affect the tone of the picture

For the tone of film and television pictures, the influence of light and shadow is the most basic and direct. For the audience, the tone of a film is the overall impression after watching the film, just like when we see someone, the overall feeling of his dress is bright or gloomy. Therefore, in a sense, the tone is the external embodiment of the way of film and television. The establishment of the tone of film and television plays a very important role in the creation of the whole film. It can make the tone of each scene consistent and harmonious. The tone is not only the external embodiment of the way of composition, but also the integration of film and television connotation.

The tone of film and television is composed of picture tone, which mainly includes shadow harmony and color. Shadow tone is the light and dark level of the shadow in the film and television picture, and it is one of the factors that constitute the tone of film and television. The tone can be composed of black, white and gray. As early as the black-and-white film era, creators paid great attention to the tone of the film. At that time, most of the settings used were colorful, and their intention was to make the black-and-white gray level richer. Today's colorful films are not only the collection of colors, but also pay attention to the black-and-white gray treatment of colors, so as to achieve the intention of having a stable tone of film and television films. In order to achieve this intention, the lighting conditions are one of the important factors. To deal with the tone of a film, we should also deal with the color, that is, the color tone. The color that plays a leading role in the film and television picture is the main tone of the film's color, also known as the color tone. It includes color difference, color lightness and color saturation. In order to restore the color of the whole film and television correctly, fit the light and shade with the content of the times and the film, and grasp the consistent color tone of the film, the treatment of light still plays an insignificant role.

Generally speaking, the projection direction of light, the nature of light and the color of light will directly affect the tone of the picture. Different light projection directions will directly affect the area of the light receiving surface and backlight surface of the subject, and the light receiving surface and backlight surface of different areas will affect the tone structure and color structure of the picture. Under the illumination of smooth light, the light receiving surface of the object occupies a large part, so smooth light is the light that constitutes the tone of bright hall. In the current film and television lighting, especially the static lighting of characters, CIS light is often used as the main light for film and television modeling, such as the lighting of news program hosts. The introduction of the great scenery of the Loess Plateau in the film "loess land" is to use natural light as CIS light to distribute light. Under the irradiation of this natural light, the yellow color of the Loess Plateau is truly restored and outstanding. This yellow color truly reflects the characteristics of the Great Northwest on the screen. The illumination function of front light and side light is used when the light receiving surface of the object is slightly larger than the backlight surface or the area of the two is almost similar, the tone structure of this light illumination tends to be bright or the center tone is dark. Taking the scene of the Eighth Route Army and the old man sitting opposite on the Kang in the loess land as an example, the lighting scheme for him is mainly 90 degree side light, which highlights the bright tone of the front of the Eighth Route Army and enables the audience to see the summary of his face. Under the irradiation of side backlight and backlight, the light receiving surface of the object is smaller than the backlight surface, and significant projection will occur. Under this light, the image tone should be darker and low. Then take the lighting of the old man in the same play in the loess land as an example. The main lighting scheme is to summarize the light, that is, the backlight, and add the top light. Using this kind of dark tone after light treatment, that is, the role of large-area dark harmony and small-area bright tone, reflects the deep wrinkles on the old man's face and describes the old man's weather beaten.

There are more and more modern colorful films. The color of light is not only richer in tone, but also more outstanding in the overall color tone of the picture, rendering the picture atmosphere together. At this time, the color light of different colors has its own place to play. For example, take a picture of a girl with long hair in the moonlight. In order to make the environmental atmosphere of the moon night more real, you can use the blue light of the lamp as the setting light. For the characters, use the main light of the blue color as the backlight to outline the generalization of the girl with long hair and shawl, and use the soft scattered natural light as the surface light to adhere to the normal color of the character's skin color. This picture gives people the feeling that it should be the night when the moonlight is scattered on the ground. The blue moonlight reflects the girl's summary. The girl's long hair is shiny, which not only reflects the girl's Leisure under the moonlight, but also highlights the blue tone of the whole picture.
