A studio is inseparable from a camera and lighting design. In order to achieve good lighting visual effects, in addition to the performance of the camera itself, it also has certain requirements for the illuminance, light ratio, color temperature, and color rendering index of the studio lighting design. As long as these basic requirements are met, coupled with a reasonable layout of lights, the effect of studio lighting design is greatly improved.
1. The camera's requirements for the studio lighting illuminance
Different sensitive cameras have different requirements for illuminance. High sensitivity requires lower illuminance; low sensitivity requires lower illuminance. According to experiments, the studio lighting design has a facial illuminance between 750lux and 1500lux, and when the camera's aperture F value is between 5 and 8, the picture restoration effect is good, meeting high-definition shooting.
2. The requirements of the camera on the overall light ratio of the studio
Studio lighting is to control the brightness range of the scene within the dynamic range of the camera, usually using a combination of hard light and soft light, soft light as the main light source, and hard light as the auxiliary light source, complementing each other, and the overall lighting has levels to make the character scene express Different styling effects and artistic atmospheres make it fit in the video screen, with contour levels, texture, and piercing eyes, which achieves a good visual effect of studio lighting.
3. The requirements of the camera on the color temperature of the studio lighting
Color reproduction is one of the important indicators of color cameras. It is not only determined by the camera itself, but also affected by many factors such as the color temperature of the lighting source and the color rendering index. For TV cameras, there are generally two color temperature levels of 3200K and 5600K. 3200 warm white usually shoots some warm and warm pictures, and 5600K normal white is usually used for high-definition shooting. The color rendering index is above 90, and the color reproduction of the shot picture is true and clear.
The basic requirements of studio lighting design are essentially reflected in the TV camera equipment. The camera requires the studio lighting to be bright enough; the light ratio should be uniform, layered, contour and texture; the color temperature should be stable, that is, the stability of the lamp should be good, whether it is a single lamp or the same kind of lamp, the color temperature should not be obvious change.
