TV station news studio lighting is different from ordinary civil lighting. Relatively speaking, its lighting technology requirements are higher. The scientific TV studio lighting arrangement can meet the needs of TV camera lighting, rendering the scene atmosphere, portraying character characteristics, and enhancing TV. The expressiveness of the show, etc. So what are the lighting technology requirements for TV studio news studios?
TV studio news studio lighting requires uniform color temperature, the color temperature of the selected lamps must be the same, the color temperature difference is more than 50K, and the shooting picture will produce color spots. At present, the color temperature of studio lighting is 3200K and 5600K, 3200K is generally used for interview studios, and 5600K is used for high-definition studios. The color temperature of the TV studio lighting should be stable, so the performance of the luminaire should be stable. The color temperature and brightness of the luminaire should not change significantly during the use. LED studio luminaires should be used.
The main light in the TV studio news studio lighting is from the side of the camera to the host. It is mainly used to express the facial shape and texture of the host. The position is 35°~30° away from the optical axis of the camera. The illumination is not Less than 1000 LUX;
Backlighting is the light projected from the back of the character along the optical axis of the camera. It is used to represent the edge and contour of the host, enhancing the sense of three-dimensionality and layering. The ratio of the main light to the main light is about 2:1, and the illumination is 2000 lux.
The side light in the TV studio news studio is used to reduce the rough shadow of the main light projection and express the dark side details. The ratio of the main light to the main light is 2:1~2:1.5, and the illumination is 1500 LUX~2000 LUX;
The background light is used to illuminate the studio background. It is necessary to reduce the shadow as much as possible. At the same time, the excess light should be controlled behind the host. The ratio of the main light to the light is between 1:1.5 and 1:1.2, and the illumination is 1200 LUX. ~1500LUX between.
TV studio news studio lighting technology requires that the color temperature of the light should be uniform and stable, and there should be no obvious changes during the use; the illumination of each type of light in the studio lighting of the TV station is based on the main light, and the illumination of the main light is not less than 1000 LUX. The light ratios of backlight, sidelight, and background light to the main light are 2:1, 2:1~1.5:1, 1.5:1~1.2:1, respectively.
