Principles of using stage lighting

The modern technology of stage lighting is often amazing. Different stage lighting brings different visual experience to the stage. Nowadays, the application of lighting is very wide. The use of stage lighting equipment and technical means to display the environment, render the atmosphere, and highlight the central character with light color and its changes can create a sense of space and time on the stage, and shape the external image of the stage performance.　The stage lighting has developed from one or two lights to one, two or even more rows. As a result, the lighting control system appeared. Through the early changes of one control lever, multiple control levers, centralized control, and segment control equipment, but these devices are still very complicated in the manual operation process, and the best state of art cannot be guaranteed.　　 In the late 1980s, with the development of electronic computer technology, the use of computers to store lighting information became more and more common to replace a large number of complicated manual operations. Entering this century, digital technology has developed rapidly, and the field of professional stage lighting has gradually entered the era of comprehensive digitalization. At present, most of the professional lighting equipment used in large-scale outdoor performances in China adopts digital control. Digital technology has brought a profound change to stage lighting. Connecting the lighting control system with digital technology makes the stage lighting control more intelligent, which adds a lot to the performance stage. Stage lighting is very important for performing arts, there are two points

1. The role of stage lighting　　1. Make the stage picture clearer, guide the audience's sight, so that the audience can see clearly or some corners of the stage will not be seen by the audience.　　2. Strengthen the effect of stage performance: meet the needs of the plot, make the background appear natural, set off, suggest and induce the development of the plot, and adjust the atmosphere (actors, audience).

  2. The principle of using stage lighting　 1. Intensity (referring to the brightness of the light): There must be enough light to enable the audience to see the color, appearance and details.　2. Distribution: Including the distribution of lighting and the direction of shooting to the stage, the main body must be different from the supporting role and the background using obviously different colors or brightness.　3. Color: Rely on colored paper, computer toning and other methods to meet the needs

4. Change: According to the actual situation, change the color, brightness and movement track of the light. In the specific use of stage lighting, before reducing a certain light source, you should make preparations to enhance the next light source. In addition to the special needs of the plot, try to avoid black sounds, so as not to affect the work of the cast and crew.
