With the increasing emphasis on education by the country, recorded classrooms have been widely used, extending from colleges and universities to primary and secondary schools. Recorded classrooms have become a new trend on campus, and therefore, the lighting requirements for recorded classrooms are gradually increasing. So how to design the lighting of the recording room reasonably and shoot high-quality video images?
Below are some considerations for lighting design in recording classrooms to meet shooting requirements and ensure comfort for both teachers and students. Precautions for Lighting Design in Recording Classroom:
1. Illumination is a basic and necessary condition for classroom photography, and classrooms should avoid using natural light sources and instead use artificial light sources. When using artificial light sources, LED conference room flat panel lamps can be selected as the light source. LED flat panel lamps have the characteristics of high light efficiency, soft light, shadow fading, no dizziness, and long service life. The face light can be selected as an embedded LED conference room lighting fixture with adjustable angles, making it easy to adjust the lighting. The lighting system is controlled by branching, and all control switches are uniformly controlled in the control room.
The illumination of the anchor classroom, for the camera area, such as the illumination of people's faces, should be 500LUX. To prevent uneven facial lighting, the embedded LED conference room lighting fixtures with adjustable angles can be rotated to the appropriate position and adjusted during the installation of the video conferencing television. For monitors and projection televisions, the illumination around them should not exceed 80LUX and should be controlled between 50-80LUX, otherwise it will affect the viewing effect. To ensure clear handwriting on files and charts, the illumination in the file chart area should not exceed 700LUX.
3. It is recommended to use a diffuse reflection light panel with a color gamut of over 85% and a color temperature of 6500K. The direction of the light is more important than the intensity of the light. Installing a diffuse lens for the light can fully diffuse the light and provide even illumination on the faces of the attendees.
4. The teacher is the main figure in the recorded classroom, and the image of the teacher during recording can lead to the quality of the course. The top light should be installed at the top position of the teacher, and the horizontal distance between the face light and the teacher should be 1200-1800mm. The face light should use adjustable angle LED flat panel lamps to illuminate the teacher's face and highlight the teacher's facial contour. The design of lighting should be reasonable, with uniform light, appropriate brightness, and no flicker or other issues with the lamps.
