In the application of night scene lighting, the first consideration is to achieve the desired effect. What kind of tone and atmosphere need to be made to meet the needs of the scene. Expressing a tone is crucial to the appearance of the visual image of the entire audience.

 In some cases, the only goal is to clearly see one or several subjects (actors or dancers), but usually this is not the case. The actual goal is quite complicated. Lights help express an emotion or guide the viewer's eyes to a specific location. It can provide greater depth to the scene and show rich layers. Therefore, when creating the lighting for the scene, you can ask yourself what tone you want to express, whether it is passionate, unhelpful, warm-hearted, absurd and playful, grand and solemn, etc.
Does the lighting set enhance the plot of the story? Whether special lighting effects are needed in the scene, and if so, should they be created with lights or through other means;
A simple example is how to grasp the effect of visible light source shining or glowing in less than 1 second; at this time, you need to specifically include them for the rendering theme, and consider how they come out, and it should be combined with music Synchronization, etc., you must have a psychological preparation and real-time grasp in advance. The most important thing is how to achieve the best combination of main light, auxiliary light, background light and ambient interference light; fully serve the atmosphere to be created, and not superfluous. The main light source is usually placed in three-quarters of the position (turned 45 degrees from the front of the subject and 45 degrees upward from the center line. This position is often used as a fixed position), but according to the needs of the specific scene, It can also come from below or behind the main body, or any other position. The key is that the main light is usually the first considered light, and use it to create preliminary lighting effects in the scene; conventionally, it is done with high-power back light or PA64-1000W; but sometimes it can be done with moving head computer lights. It has better effect than conventional lamps; especially under or behind the main body, or any other position, it is much more free and flexible than conventional lamps.
 Although the initial placement of the main light source provides a good way to illuminate the object, the result is indeed a monotonous and boring image. The shadow is usually very thick? Consider how to overcome his shortcomings. After all, the main light is the most noticeable light source in the scene, so be careful. Supplementary light is used to fill the dark and shadow areas of the scene, which can provide depth of field and a realistic feeling. The more important supplemental light comes from diffuse reflection; part of the reason why this type of light is important is that it improves the color brightness of the entire scene. Unfortunately, if the auxiliary light is over-rendered, it will reduce the overall darkness of the scene, eliminate some possible characteristics, and cannot model any light and shadows on the illuminated subject, which makes the scene look unrealistic; Therefore, place low-intensity spotlights or floodlights in a reasonable position in the scene.
This type of auxiliary light should reduce the shadow area and add some light to the bottom and corners that cannot be directly illuminated by the key main light. In order to achieve the desired effect. Background light is usually used as "edge light", which may increase the credibility of the scene by illuminating, but the background of most night scenes is fixed, and it has little auxiliary effect on the track in the performance, so use it sparingly; of course, at the beginning It is very proud to use it well. In addition, ambient interference light refers to the lighting in the venue. Natural scattered light or ambient diffuse light softens the light effect of the stage (pool). It is difficult and conflicting light in lighting management. It is best to reduce its brightness as much as possible. Yes; but sometimes you can also take advantage of your strength, it depends on your performance on the spot.
