On the Playing Method of Photographic Lighting

1, three-point lighting: main light, background light and auxiliary light.

2. Main light: In front of the object, it mainly illuminates the main object in the scene and its surrounding area.

3. Auxiliary light: increase the contrast between layers of the main body.

4. Background light: 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. Anyway, the background and objects are layered.

1, main light:

The main light is the main illumination light of the object, which plays a leading role in the expression of the shape, outline and texture of the object. When shooting, once the main light is determined, the basic light and tone of the picture are determined. It should be noted that for a subject, there can only be one main light. If several light sources are used as the main light at the same time, the subject will either receive the same light and can't tell what the main light is, and the picture will be dull; Or several main lights produce shadows on the subject at the same time, and the picture appears chaotic.

2. Auxiliary lights:

The main function of auxiliary light is to improve the brightness of the shadow part produced by the main light, so that the dark part also presents a certain texture and level, and at the same time reduces the contrast of the image. In the application of auxiliary light, it should be clear that the intensity of auxiliary light is less than the intensity of main light, otherwise it will lead to the effect of usurping the role of the master and easily produce obvious auxiliary light projection on the subject, that is, the phenomenon of "light clamping".

3. Side lights:

Side light is the light used to outline the main body. Side light gives the subject a three-dimensional sense and a sense of space. Backlight and side backlight are often used as side light, and the intensity of side light is often higher than that of main light. A dark background helps to highlight the side light.

4, decorative lights:

Decorative lights are mainly used to decorate parts of the main body or to show the details of the main body. Decorative lights are mostly narrow light. Eye light, luminous light in portrait photography and flare of the first ornament in commodity photography are typical decorative lights.
