How to hit 3D indoor lighting to achieve the best effect?

According to the following lighting principles, 3D indoor lighting can achieve the best effect:

1. The process of setting lights is simply called "lighting". Although a complex scene is illuminated by 100 lighting technicians, there will be 100 different schemes and effects, but everyone will abide by several principles of lighting. For indoor renderings and indoor photography, there is a famous and classic lighting theory, which is "three-point lighting".

2. Three-point lighting, also known as area lighting, is generally used for small-scale scene lighting. If the scene is large, it can be divided into several smaller areas for lighting. Generally, three light zones can be used, including main light, auxiliary light and background light.

3. Main light: it is usually used to illuminate the main object and its surrounding area in the scene and play the role of projecting the main object. The main relationship between light and shade is determined by the main light, including the direction of projection. The task of the main lamp can also be completed with several lamps as needed. If the main light is in the position of 1.5 degrees to 30 degrees, it is said to be smooth; At the position of 45 degrees to 90 degrees, it is called sidelight; It becomes a side backlight at the position of 90 degrees to 120 degrees. The main light is usually made of spotlights. I like to set the brightness of the main light at around 240. ?

4. Auxiliary light: also known as fill light. The fan-shaped reflector is illuminated by spotlight to form a uniform and indirect soft light source, which can fill the shadow area and scene area missed by the main light, reconcile the contrast between light and dark areas, and form a sense of depth of field and layering. In addition, this wide and uniform light distribution makes it lay the background color for the scene and define the tone of the scene. In order to achieve the effect of soft lighting, the brightness of auxiliary light is usually only 50%-80% of the main light.

5. Background light: Its function is to increase the brightness of the background, thus setting off the subject and separating the subject and object from the background. Generally, floodlights are used, and the brightness should be dark but not too bright.
