Lighting Differences between party performance and TV recording

Absrtact: Stage lights – stage design – party performance lighting are based on the stage design and the scene, which are designed for design creation according to the main program. On stage you have to ensure the appropriate degree of the light, color, illumination that are specifically designed for the audience to watch the performance.

The lighting engineers have to pay attention to the control of the TV recording cameras as the light ratio, color temperature requirements are different from stage performance and they have to take the multi-camera shoot into account, to design a program to meet the lighting television filming techniques.

1. The differences in Live performances and television viewers

Live performance is a direct speech to the audience to see, so the most direct thing is human eye. What TV audience saw were some pictures filmed by the camera in live performances, namely, the camera has seen the picture instead of the human eye. The director tried to reproduce the scene to the maximum extent possible by switching different sites and different views.

2. Different requirements of controlling lighting between stage performances and television performances.

Stage performances emphasize the theatrical sense of the scene and emphasize the atmosphere. The at-mosphere rendering is showed by the brightness of light in the performance. Perception of the human eye to light is very wide, even the faint light can be identified. TV performances need to have a certain illumina-tion degree and appropriate light ratio to make the light spread evenly. When the program consider the full range of light, you need to combine camera technology with the characteristics to a more detailed dis-tribution of light. With the development of science and technology in recent years, high-definition broad-cast technology has been widely used, greatly reducing the requirements for the degree of controlling illumination. The average illumination control stage performances around 500LX, light ratio control in 7: 1, also allows the screen shot of tone, color and tonal gradations having a good picture effect.

3.Different Light Ratio

Theatrical lighting pay more attention to the strong contrast to the light and the light ratio would be great. According to needs of the plot, you can pull a big light ratio between different scenes, to show stage effects and spatial levels.The requirements of TV lighting are more demanding than the stage lighting and must care about on issues on the light ratio in recording. The light projection angle, the brightness of light and shade need to make fine adjustments on the premise that the overall effect will not be ruined.

4. Different color temperature requirements

TV has very strict requirements for color temperature, the lighting effects we see in the TV picture is different from what kind effect we see in the live scene. Especially in the case of recording a low color temperature program, the lamp with high color temperature light source like computer lights will obviously cast.

5. Different color rendering

No color, there is no atmosphere. The use of shade is largely based on a specific theme to take advantage of the effect of colored light manufacturing, heighten the atmosphere. The use of warm and cold, light and bright in colors can present the stage depth, atmosphere and mood. The color light in both performances and stage play can be concentrated to either light or bright.The use of shade and color should meet the aesthetic ideas of the people, and should make the actor clothing, makeup and other scene elements in unity.

b. In the premise of maintaining illumination, lighting evenly as possible, proper control of light ratio and avoiding the strong contrast are all to make the picture a unified soft and try to ensure TV recording under the premise of stage effects;

c.Identify specific environment light, such as hosted area lighting, props light, dance scenic light, so that it can highlight;

d.Sidelight and backlight play the role of contrast. Colors should be light instead of dark, and backlit illumination must be more than the main light.

Pay attention to the coordination of choreography, clothing, makeup, big screen, color screen and other elements. The actor make-up should be simple. Under normal circumstances, surface light should not be shady. Choreography, props, big screen and screen content had better not use high brightness, highly reflective and black material. Experience has shown that, during the TV recording, if the surface light color temperature is 4000k-4500k, with 18 degrees of gray on a white balance, TV screen recorded will be relatively transparent and the characters are more beautiful.
