The Question About Design Stage

Stage lighting is one of the means of stage beauty modeling. By using certain scientific and technological means, according to different plot development, and under different stage lighting mapping, it can play the role of highlighting the psychological changes of characters or rendering the atmosphere. Stage lighting is the finishing touch of a performance, so stage lighting design is particularly important. The editor will introduce some problems that should be noticed in stage lighting design for you today.

01 How to set the type of scene lights

Scene lights are generally divided into three types: natural light, artificial light or a combination of both.

In fact, natural light is what we call sunlight, and there are three problems to pay attention to when using sunlight: time, weather, and the light and shade of the light source. But Xiaobian thinks it is difficult to use the natural light, because many times you can only

Artificial light is the opposite of natural light. Artificial light is the most common and common of the three light sources. Lamps, stoves or some objects that can emit light are recognized as artificial light as long as they can illuminate the surrounding environment. However, it should be noted that the source and quality of light should be considered when using artificial light; If there are several light sources, it is necessary to clearly distinguish what the main light source is and determine whether the light source has color light. It should be noted that almost all light sources have one or more colors, not only pure white.

The last light type is the combination of natural light and artificial light. When shooting in a bright outdoor environment, the photographer or lighting engineer will use a reflector or auxiliary lamp to alleviate the harsh shadows.

02 Purpose of using lighting design

Basically, what is the tone and atmosphere of the scene, which is related to the most important lighting. In some cases, the only goal is to clearly see one or more objects, but the reality may become very complex.

Lighting can help to express emotion, or guide the audience's sight to the characteristic position, or let the audience form a special visual effect, which can provide greater depth for the scene and show a sense of hierarchy. Therefore, what tone should be expressed in the lighting design, and whether the designed lighting can better enhance the depth level.

03 Reference materials for scene design

When creating realistic scenes, we should form the habit of drawing materials from actual photos and films. Reference materials can provide you with better clues to clearly understand how specific objects or environments need to use light at different times of the day. Careful analysis of light distribution can better adjust the basic position and intensity of light. Although the number, type and individual attributes of light sources will vary from site to site, there are three basic types of light sources: key light, supplementary light and background light, which work together in coordination.

04 How to use key lights

The key light is the most important light source in a scene. The key light is not necessarily just a light source, but the key light is the main light source of the photo. Similarly, key lights are not necessarily fixed in one place like point lights.

Although the point light source is usually placed at three-quarters of the position (45 degrees from the front of the object and 45 degrees from the centerline, which is often used as a fixed position), it can also come from below or behind the object, or any other position according to the needs of the specific scene. The key light is usually the light source placed first, and make it establish the preliminary light effect in the scene.

Although the initial placement provides a good way to illuminate objects, the result is really monotonous and uninteresting. Shadows are usually rough and very visible. Similarly, the scene always looks too dark because there is no natural light to set off the shadow area. It will still be useful in certain scenes, but it is not suitable for most pictures.

05 How to use supplementary light

The supplementary light is mostly used to fill the dark and shadow areas of the scene. The supplementary light can provide the depth of field and realistic feeling.

The more important supplementary light comes from natural slow refraction. This type of light is usually called ambient light. This type of light is important in part because it improves the brightness of the entire scene, but the ambient light of most renderers is uniformly applied to the entire scene. Although it reduces the overall darkness of the scene, it eliminates some features that may be used, and cannot model any light and shadow on the illuminated objects, which makes the scene look unrealistic.

The best way to simulate ambient light is to place low-intensity spot lights or omni lights in a reasonable location in the scene. In addition to the natural scattered light or ambient light in the scene, supplementary light is used to illuminate too dark places or emphasize some parts of the scene. They can be placed in the relative positions of key lights to soften shadows.

06 How to use backlight

Background light is usually used as "edge light" to separate the target object from the background by illuminating the edge of the object. It is better to place it directly opposite to three quarters of the key light. It acts on the edge of the object, causing a small reflective highlight area. This kind of highlight will make the object increase the authenticity of the scene.
