Because of the controllability of artificial light sources, in principle, only one light source can be used. Artificial light sources can be dedicated LED studio lamps for TV stations. LEDs are cold light sources with high luminous efficiency and low heat, energy saving and environmental protection. Avoid the use of traditional light sources (heat light sources), high power consumption, heat generation and inconvenient use.
2: Illumination requirements for lighting
Under normal circumstances, campus TV studios use good-quality cameras with illumination not less than 600 lux. The color temperature is 3200K to 5600K. Most of the studio color temperature is 3200K, and the pictures taken are real and clear. Some of them are used for high-definition recording using 5600K. LED studio lamps CRI≥92, high color reproduction.
3: Method of lighting
Surface light: Generally, the appropriate projection angle is ≤45°, avoid flat light on the front. Face light is to illuminate the host’s face evenly and delicately; background light: brighten the entire background to make the picture look clearer, separate the host from the background, and emphasize the image of the host; contour light: make the outline of the host obvious , Highlight, improve the overall picture effect of the character image; top light: increase the texture of the host’s hair and supplement the light source of the shoulder; side light: soften the dead corners and shadows that are not illuminated by the main light, and soften the shadow of the host’s neck .
