Briefly describe the characteristics and types of digital lights for stage film and television

There are many ways of lighting the studio, and we can choose a suitable lighting method according to the specific situation of the studio. First of all, we need to clarify the classification of studios. Studios can be divided into three categories according to the project area: large (over 400 square meters), medium (about 150 square meters) and small (below 50 square meters). Large-scale is mostly used for singing and dancing, drama Classes, variety shows, stage plays, etc., medium-sized are generally small operas, quizzes, symposiums, etc., and small are mainly news, program previews, interviews, board teaching and other programs with little action. Different program types, the number of hosts and guests is different, and the lighting arrangement is also different. Here are several lighting methods:

a. Three-point lighting, that is, using main light, backlight, and auxiliary light to express the theme;

b. Multi-key light distribution, which can show the main light source for various positions of the camera;

c. Soft front light, strengthen the effect of backlight, so that the illumination of the entire performance area is relatively uniform;

d. Use side key light, hard light from both sides of the set, to provide side key light and side backlight. fill light from the front of the set;

e. Overall lighting, basic lighting first, (called general illuminance in TV, this illuminance is 800-1500lx.) The color of the camera can be basically reproduced, and then three-point lighting (multi-main light, multi-backlighting) is used. , multiple auxiliary lights). The illuminance of multiple key lights should be consistent, as should the backlight and fill lights. Similarly, the color tone of the image captured by the camera at the designated position should be basically the same;

f. Hierarchical lighting, the studio's music and song and dance programs use hierarchical lighting, also known as zoned lighting. This lighting method enhances subject and perspective. The layered lighting can be divided into front area, middle area and rear area. The illuminance of these three areas is different. The illuminance of the front area should be 2000~2500lx, the illuminance of the middle area should be 1500~2000lx, and the illuminance of the rear area should be 2000~2500lx. At 800~1000lx, the illuminance of the skylight should be 600~800lx. The purpose of zoning lighting is to give people a sense of hierarchy and three-dimensionality.
