LED panel light lighting skills
1 Lighting in the form of station broadcast
Station broadcasting is an important form of news programs, and there are many cases in various types of programs such as information, weather, interaction, and comments. Station broadcasting is more flexible than other broadcasting methods. Usually with a large screen or light box as the background. When a single person broadcasts at a fixed point, the lighting can be based on "three-point lighting", and each position uses 3 to 5 LED panel lights; if it is a walking broadcast within an area, you can use the panel lights to make a continuous broadcast. Uniform surface light area. According to the size of the walking range, a flat panel light can be arranged at a width of about 1.5 m for surface lighting. Backlighting Choose a flat or spotlight based on the size of the moving range and the height of the studio floor. The main direction of the surface light is the same as the direction of the camera. The distance between the host and the large screen background should be more than 1.5 m. If it is a large-pitch LED screen, the distance should be larger depending on the situation to avoid camera moiré and stray light from interfering with the screen.
2 Lighting in the form of sitting
Sitting broadcast is a multi-purpose program form for current affairs news, people's livelihood news, and interview programs. There are different lighting methods for single, double and multiplayer. Single-person lighting is usually improved on the basis of "three-point lighting", which can create uniform lighting for the host by increasing the number of panel lights and improving the angle. For the lighting of the surface light, each host uses 3 to 5 LED panel lights as the main surface light and side light of a single host. Backlighting can use LED spotlights or LED imaging lights with the same color temperature, which is more effective for regional control of the light zone and the contour lighting of the host. Use eyelights under the deck of the broadcast table to lighten the shadows on the host's face. When lighting for two people and lighting for multiple people, it is necessary to consider the specific role of the directionality of each lamp. Sometimes it is necessary to consider the use of one lamp for multiple purposes, for example, as a side light for host A, and also for the backlight of host B; sometimes it is necessary to use a dedicated light, in the case where two or more hosts are sitting close to each other. Down. Use shutters and black flags to prevent stray light from affecting other presenters' faces.
Some news programs require the host to rotate angularly according to different camera positions during the program. For example, a medium shot is one angle, and a close-up shot is rotated within a range of 5° to 15°, or even larger. At this time, it is necessary to consider the lighting layout of different lenses, for example, whether two lighting programs are required according to the rotation, or the main lens is the focus of the lighting.
3 Virtual/Keying
The following points should be noted when lighting a virtual blue box or green box:
The movement range of the host should not be too close to the wall, keep a certain distance, and avoid the influence of blue or green reflection on the host;
The lighting of the box should be uniform. The illumination of the box should be slightly lower than the illumination of the characters;
If there is a combination of virtual and real scenes, it is necessary to pay attention to the consistent illumination of the combination point and avoid dark areas.
4 Precise lighting programs
Often the appearance of the host is not the same. When programming the lighting program of each program, the light of each host should be fine-tuned according to all the hosts of the program. For example, a host with a fuller face can reduce the brightness ratio of the side light; for a host with a thin face, the brightness ratio of the side light should be increased; the host with a more “eating” hairstyle should increase the brightness of the backlight, and the hairstyle is easy to reflect. The presenter reduces the brightness of the backlight, and so on. For each host of each program, the lighting program must be more refined and targeted.
