The role of LED white light in recording programs
The use of LED white light for face light, slap light, column light, top light, mobile light, etc., also solves the problem of uneven color temperature and solves the problem that the color temperature of the surface light changes with the change of illuminance. Because the color temperature of the LED white light does not change with dimming, its color temperature is relatively fixed. Practical experience tells us that when the white light color temperature of the surface light is around 4200K, the recording effect and the stage performance effect are ideal. This is easy to do for the LED white light lamp, which brings great convenience to our work. The emergence of the new LED white light has created conditions for us to solve the different effects of theatrical performance and recording, and provides an opportunity to solve this problem.
LED white light brings us convenience in terms of color temperature uniformity. In theatrical performances, the surface light, slap light, column light, top light, and mobile light used on the stage are almost all tungsten lamps. The color temperature of these lamps is low, generally at 3200K. Some lamps use computer lights, LED par and LED dyeing lights, and their color temperature is higher, generally 5600K. In this case, the color temperature will be unbalanced in theatrical stage performance. There will be no big problems for the audience in theatrical stage performances, but there will be big problems in the recording, which will cause great inconsistencies between the stage effect and the recording effect in the performance. Bring a lot of trouble to work.
The recording of TV programs is different. In the recording of pure TV programs, the illuminance of the surface light is basically the same, and the color temperature does not change. The stage performance is different. This is also the difference between the lighting changes in theatrical stage performance and the recording of TV programs, and it is also one of the reasons why the theater stage effect is different from the recording effect. Nowadays, almost all theatrical stage performances are recorded. Solving the problem of uniform color temperature also basically solves one of the problems that theatrical stage performances are different from the recording effects.
