Small and medium studios have put forward special requirements for studio lighting.
Compared with traditional studios, there are a series of problems to be solved in lighting. (1) The illuminance of the studio is 1500-2000ix according to the standard image specification of camera, and editing and other post-production machine room of the illuminance contrast such as bad processing, it is easy to make the video camera output can not reach the broadcast level requirements, or although the announcer's image to meet the requirements, but the background is ambiguous. In particular, the production of small and medium-sized studio background is very easy to make the editing room to form a "black hole", if simply increase the illumination of the editing area, will make editors in a strong glare work, very uncomfortable.
So the production room and studio lighting to design reasonable. (2) The lighting of the editing room has no requirement for the color of the light source, and the color temperature of the TV camera is 3200K (the cold light is 300K), the color-rendering index requires more than 85 (preferably in 90).
To use professional studio three-color lighting lamps to achieve the lighting requirements of television cameras, lighting design needs reasonable selection. (3) Edit Office room lighting, should only feel the normal brightness, and should not glare glare, that is, staff in normal working and head-up, do not see the light source.
and studio lighting in order to meet the TV camera image level and contour clear, requires a certain angle, lamps relative "bare." (4) Studio background with a circle of curtains or background board processing, broadcast area and background editing area in the same layer, the background is real, there is a virtual, the requirements of the lighting is completely different, background light if not handled well, television image is prone to dazzling brightness contrast.
Therefore, there are certain restrictions on reinvestment to do a reasonable distribution of lighting adjustment, as long as a good deal even if the use of a background light can be, so relatively little investment.
