1. Visual effects in the process of lighting changes

The form of change reflected by the change of light is the change of light area from one kind of space to another; the change of light quantity from one kind of brightness to another; the change of light color from one color to another. These are the three basic forms of lighting changes. The three are usually mixed visual effects. Therefore, in the control of light zone, light quantity, and light color, attention should be paid to the matching of light ratio and the relationship between characters and characters in different spaces.

There are gradual changes and sudden changes in the light, which are related to the length of the change. The duration of this process depends on the rhythm of the plot, the rhythm of performance scheduling (or screen scheduling), the rhythm of music (or sound effects), and the tolerance of lighting technology. It needs to be explained here: Speed and rhythm, as the dramatic effect of change, are a complete concept in the audience's visual experience. The expansion of stage actions and the analysis of changing techniques are two concepts. Speed is the response of the time process, and rhythm is the reflection of the emotional process, a combination of external and internal.

2. Light changes and dimming technology

Stage dimming is an important tool for organizing lighting changes. It is the main executive body of performance lighting control and the central nerve of the lighting control system. Contemporary stage dimming equipment has greatly exceeded the concept of "dimming". It also controls various lighting machinery related to light changes and non-dimming light source control. In fact, it has developed from the concept of "dimming" to "stage lighting system". Control concept.

3. Human operation quality

Although the control technology is advanced, it can be highly automated and programmed. But theater lighting art cannot press a button once at the beginning of the show, and it can operate automatically until the end of the show. Theater art is not a factory product. Performance is that emotions and emotions control the movement of time and space, and the lighting control is synchronized with the performance. The lighting changes of the performance will ultimately depend on the lighting operators to complete. Faced with the development of high-tech dimming equipment, the artistic concept of lighting design will become more and more complex in the future. Therefore, regardless of the factors of art and technology, lighting operators must constantly challenge themselves with the development of the times.
