When making the lighting layout of TV stations and primary and middle school studios, in addition to meeting the video shooting requirements of the entire studio, it is also necessary to consider how to cooperate with the host in the lighting design. The host’s skin color and clothing will affect the placement of the studio lights. And the adjustment of light brightness. The following editor will teach you how to set up the studio lighting design.

The lighting layout of the studio must first determine the area of the studio. Generally speaking, large studios above 300 square meters, medium-sized studios between 100 and 300 square meters, small studios below 100 square meters, like general school studios. The hall is generally about 30-60 square meters; secondly, the lighting technique should be selected according to the type of studio, such as virtual studio, real-scene studio, interview studio, panoramic studio, etc. The lighting configuration methods are different. However, the principle of supplementary lighting in the studio is to distribute the light in all directions, without vignetting, to ensure the shooting effect.

　　 three-point lighting

　　 Three-point lighting, that is, the main light, backlight, auxiliary light (slap, etc.) are used to express the theme.

　　 Multi-primary lighting

　　Multi-primary light distribution, which can show the main light source to various positions of the camera.

　　 soft front light

　　The front light is soft, and the backlight is strengthened to make the illumination in the entire performance area more uniform.

　　 side main light

　　Using the side main light, the hard light from both sides of the set, the side main light and the side backlight are provided, and the auxiliary light comes from the front of the set.

For overall lighting, the basic lighting is first (called universal illuminance in TV, this illuminance is 800～1500lx) so that the color of the camera can be basically reproduced, and then three-point lighting (multiple main light, multiple backlight, multiple auxiliary lights) Light). The illuminance of multiple main lights should be the same, as are the backlight and auxiliary lights. Similarly, the tones of the images captured by the camera at the specified location should be basically the same.

　　 Hierarchical lighting, the studio’s music and song and dance programs use hierarchical lighting, also known as zone lighting.

　　This lighting method can enhance the subject and perspective. Hierarchical lighting can be divided into front area, middle area and back area. The illuminance of these three areas is not the same. At 800～1000lx, the illuminance of sky curtain light should be 600～800lx. The purpose of zone lighting is to give people a sense of hierarchy and three-dimensionality.

　　 Indoor daytime scene lighting

　　Indoor daytime scene lighting, strong light should be used to project the shadow of the window into the room to replace the effect of sunlight. The direction of the main light should be consistent with the direction of the sunlight to make the picture effect more realistic. The position of the auxiliary light should be at 70° to the camera, so as to eliminate the long nose shadow of the character. It is advisable to use LED film and television flat-panel lights for the scenery, the light is soft and uniform, so that the scenery presents layers.

　　 Indoor night scene lighting

　　Indoor night scene lighting, generally chandelier is used to illuminate the whole room, desk lamp is used to illuminate the desk, and wall lamp is used to illuminate a part of the room. These kinds of lights are good for expressing the light effect of the environment and the characters. The best way to express the atmosphere of the indoor night scene is to turn on and off the lights. The audience is very sensitive to know that it is night. To deal with the light of turning on and off the lights, firstly turn on the light when the lights are turned off, and then turn on the light after turning on the lights. The light when the light is turned off is darker than the light when the light is turned on. The room appears dark but it can make people see the outline.

　　1. Avoid flat light on the front and use light from the side or back. As long as the light source is next to or behind the camera, it is likely to produce flat, non-stereoscopic light. Because if the front flat light is used improperly, there will be logical errors in the projection environment, and the inconsistency between the actual light source and the virtual light source; in addition, the secondary projection produced by the main light source on the blue box will also affect the computer's image processing.

　　2. Use techniques such as backlighting, strong condensing, and background ambient light to separate the host from the background, emphasize the image of the host, and create a three-dimensional image effect. The reasonable use of backlighting can well reflect the relationship between people and the scene, thereby enhancing the sense of depth and enhancing the three-dimensional effect.

　　3. Please pay attention to the shadows and use them to create contrast, depth, scene and mood. Don't be afraid of the shadows, some photographers will say "...the light that is not turned on is as important as the light that has been turned on".

　　 4. Use lighting and exposure to set the overall tone of the scene-this must take into account the reflection coefficient of the scene and the intensity of the light. Different intensities of light can render different atmospheres. For example, the light with a color temperature of 3200K is warm white light, which renders a warm atmosphere; the light with a color temperature of 5600K is white light, and the atmosphere will appear serious.

　　 5. Whenever possible, try to light up the characters from the backcourt. It can highlight the characteristics of the characters and enhance the three-dimensional sense of the characters.

　　6. When appropriate, use light barriers, cookie sheets and other techniques to add texture to your lighting.

　　7. For the installation method, if the floor height of the studio is 3.3~5 meters, the track installation method is adopted; if the floor height is lower than 2.5~3.3 meters, the grape rack and fixed hanging installation method can be adopted.
