What do you mean by main light and supplementary light?

Main light and supplementary light are two kinds of light sources commonly used in photography. The main light refers to the main light source of the subject, and the supplementary light is an auxiliary light source added to make up for the insufficient illumination of the main light. The combination of the two can help photographers create more ideal shooting effects. The use of main light and supplementary light needs to consider many factors such as shooting environment, light source angle, color temperature and lighting type. This is an important content that needs to be carefully studied and mastered in photography skills.

Main light and supplementary light are also very important in film and television shooting. Through the reasonable combination of main light and auxiliary light, the film picture can be more layered and dynamic, leaving a deeper impression on the audience. In terms of lighting arrangement, the main light is generally placed at the angle in front of the camera to illuminate the face and theme of the protagonist, and the auxiliary light is mainly used to supplement the weak light, make models, music and dance scenes and other local areas that need to be emphasized. Through the rational use of main light and supplementary light, the film picture can be more crystal clear and the details more vivid.

Main light and supplementary light are not only useful in film and television shooting, but also have many applications in daily life. For example, home lighting often needs to choose the main light and supplementary light, and the indoor light is dim. If you only rely on natural light, the picture will be too dark or too bright. In bathrooms, bathrooms, kitchens and other environments that need strong lighting, supplementary lighting can help us reduce the appearance of shadows and make the use environment more comfortable. Therefore, both the main light and the supplementary light are very common and useful shooting techniques in film and television shooting and daily life.
