The television studio is generally divided into large, medium, and small sizes according to their functions. Large studios are used for grand events such as singing and dancing, plays, variety shows, and television dramas. The large space can be divided into several small areas to shoot scene by scene, and the already shot scenes can be replaced with a different background without moving the set to improve the studio's utilization. Medium studios are suitable for small-scale drama, singing and dancing, intellectual competitions, or discussion forums. They are also suitable for television stations to produce image-oriented educational programs or plot-driven educational films. Small studios, on the other hand, are used for low-action programs such as news, program previews, and demonstration-style education. They are mainly used for inserts, voiceovers, and photography of small objects.
1. Television Studio Lighting Design
The studio used to be widely used for recording TV programs, but with the advancement of scientific technology, enterprises and schools also often use the studio to enrich the lives of their employees or students and promote their image. To ensure the clarity of the recorded images, the lighting design of the studio plays a decisive role.
2. Lighting Design Requirements for Television Studios
Small and medium-sized studios have special lighting design requirements. Compared with traditional studios, there are a series of problems that need to be addressed, such as:
(1) The illumination of the studio according to the camera standard drawing is required to be 1500-2000IX, while the contrast of the modification and other post-production rooms may be poorly processed, which can easily make the video signal output by the camera fail to meet the broadcast-level requirement, resulting in blurry background, even though the announcer's picture meets the requirements. Especially for small and medium-sized studios, the background production room is prone to become a "black hole". If the illumination of the modification area is increased, the modification personnel will be working under intense glare, which is uncomfortable. Therefore, the design of led tv studio lighting in the production and studio rooms should be reasonable.
(2) The lighting of the editing room does not have any requirements for color temperature and color rendering index of the light source, while television filming requires the lighting color temperature to be 3200K (cold light source 300K), and the color rendering index requires to be above 85. Professional studio lighting fixtures are needed to meet the lighting requirements of television filming, and the lighting design needs to be properly selected.
(3) The lighting in the editing office should only feel the normal brightness and should not have glare. The workers should not be able to see the light source during normal operation and viewing. However, the tv studio lighting design needs to have a certain angle to meet the requirements of the level of the television filming picture, and the lamps should be relatively "exposed".
(4) The studio background uses a curtain or background board to form a circle. The announcer area and the background editing area are at the same height, and the background is both real and virtual. The requirements for LED video lighting are completely different. If the background light is poorly processed, the brightness contrast on the TV screen is easily eye-catching. Therefore, when the investment is limited, reasonable allocation and adjustment of the lighting fixtures are necessary. Even if only one background light is used, it is enough as long as it is well handled.
