The role of stage lighting in stage lighting design requires that the lighting design should not only have the overall overall thinking, but also have local treatment, not ups and downs, but also highlight the changes of major areas one after another. The light source of stage lighting is white light, and the color is changed by the color filter inserted in front of the lamp. This kind of color light is projected on clothes, scenery, props and makeup of characters, which will cause color changes and belong to subtractive mixing. The influence of light color on the color of objects (makeup, clothing, scenery, etc.). ) That is, when light shines on an object with the same hue, the color of the object will become more vivid and beautiful. When light shines on an object that is complementary to its hue, the color of the object will become dark, gray or even black. If the light color and hue are not exactly the same but close, the color of the object will become brighter, and if the light color and hue complement each other, the color of the object will become darker. The following are the changes in the influence of several main light colors on search.
(1) red light. Yellow objects feel red, green objects are slightly dark, cyan objects are dark, purple objects turn red, and red objects are bright.
(2) under the yellow light. Green objects feel yellow, cyan objects feel turquoise, purple objects feel brown, red objects feel yellow and yellow objects are bright.
(3) Under the amber light. Red things remain unchanged, yellow things become thicker, green things have yellow floating light, purple things turn red, and flesh-colored things become brighter.
(4) under the green light. Red objects are stained with green floating light, purple objects feel brown, yellow objects are yellow-green, cyan objects are dark, and green objects are bright.
(5) Under cyan light. Red objects feel purple, yellow objects feel brown, green objects are dark, purple objects are blue-purple, and cyan is bright.
(6) under the purple light. Red objects feel purple, yellow objects feel brown, green objects are dark, cyan objects are full of red floating light, and purple objects are bright.
Analysis of stage lighting of different performance types In stage photography, the intensity of lighting changes frequently, and it changes with the change of plot, sometimes bright and sometimes dark. Sometimes, in order to render the atmosphere, various lighting effects are used to make the stage present colorful scenes. If you want to shoot good stage stills, you must understand the characteristics of stage lighting and be aware of it, so as to gain the initiative of stage photography.
(1) Actual performance. Such as fashion design competition, fashion trend conference, brand clothing display and other performances aimed at highlighting the clothing itself. This kind of performance emphasizes the modeling of lighting, and pays attention to the texture effect, layering and modeling of clothing. In order to better reflect the true color of clothing, colored light is not suitable. The brightness and contrast of light should be used reasonably. We can't blindly pursue the creation of stage atmosphere, which will affect the real effect of clothing.
(2) entertainment performances. As an appreciation performance, entertainment costume performance only has the external form of costume performance. The main purpose is not to highlight clothes, but to set off the entertainment atmosphere. In this kind of performance, the use of lighting should pay attention to creating a unique artistic atmosphere that matches the theme of the performance. For example, laser and strongpoint can be used to highlight the flowing sense of space and strong visual effects.
Classification of stage lighting According to the optical structure, stage lighting can be divided into three categories: floodlight, spotlight and sliding light. According to the position installed on the stage, it can be divided into surface light, palm light, foot light, column light, top light, skylight, ground light and streamer.
(1) floodlight system. Refers to a lamp that can emit uniform and soft light and illuminate a certain direction. Independent floodlights, ceiling lights, footlights and curtain lights are usually used to illuminate the sky, painting scenes or performance areas.
(2) concentration system. Refers to the lamps that can emit directional light and control the range of light area. Generally, different light spots are projected through the lens by using the refraction principle. For example, a soft lens with a thread can be used to produce a light spot with a soft edge.
(3) Slide show system. It refers to a lamp that adds a set of objective lenses in front of a spotlight to project light and image. This kind of slides can be divided into: projection slides using slide imaging. A projection slide that projects moving images such as clouds, water and fire onto a scene by rotating a disk chain belt. Once color light is used in stage performance, it will inevitably change the actual brightness on the stage. The actual brightness of the stage lighting must be tested when shooting to ensure the correct exposure when shooting. Generally speaking, color light shooting requires 2 ~ 3 levels of aperture opening than white light shooting. In addition, there are spotlights that use long focal length objective lens to make small spots clearly image and highlight the image of the protagonist, and return light that uses reflective optical structure to realize the focusing effect.
The effect control of stage lighting has four controllable attributes, namely brightness, color, distribution and movement (referring to the change of lighting). The following are some major lighting effects:
(1) The effect of the skylight. The awning is located behind the stage and has a large area. Therefore, when the sky curtain light changes with the light color in a large area, it will make the audience have different associations with the change of light color.
(2) the effect of spotlight. A spotlight is the light from the front of the stage that rolls with the actors. This kind of lamp is mainly used for close-ups of stage figures.
(3) Backlight, side light and top light effects. The backlight is behind the model and has the effect of stage silhouette. The light source of sidelight is located outside the model, which has the effect of mixing light and shade. The top light is emitted by a lamp hanging from the top of the stage, similar to the highlights in painting and the silhouette light in photography. Can add luster to the characters, especially when used in close-up modeling, can play the role of finishing touch. The ceiling lamp and backlight can increase the transparency of the stage, which can not only realize large-area lighting, but also be suitable for local and regional lighting. Especially when the performance area needs bright brightness and the whole venue is too bright, the top light and backlight must be treated.
