Indoor portrait photography cloth lamp

They are main light source, auxiliary light source and side light source.

A complex scene will have 100 different schemes and effects to be distributed by 100 lighting technicians respectively, but the basic principles of light distribution are common. For indoor photography, there is a famous and classic lighting theory, which is "three-point lighting". Three-point lighting, also known as three-point lighting, is generally used for lighting small-scale scenes. (If the scene is large, it can be divided into several smaller areas for lighting. ) Generally, there is a three-light area, which is composed of lighting in different positions. They are main light source, auxiliary light source and side light source.

As the main light source to illuminate the object, the main light source is usually the brightest light source and will determine the position of the shadow. It is usually used to illuminate the main object in the scene and its surrounding area, and project the main object. The main relationship between light and shade is determined by the main light, including the direction of projection. The light level of the main light, such as the position of the main light at 15 to 30 degrees, is called smooth light; 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.

Also known as supplementary light, it is a kind of uniform and indirect soft light source, which is used to fill the shadow area and scene area missed by the main light and to reconcile the contrast between light and dark areas. In order to achieve the effect of soft lighting, the brightness of auxiliary light is usually only 50%-80% of the main light. Location of auxiliary light: the other side of the main light.
