What are the requirements for light in portrait photography?

Portrait photography is not as difficult as expected, and you need to master the basic knowledge of light use before getting started.

1. Choose light, the texture and color temperature of light are different in different regions and different time periods. Then the traditional indoor studio lights should choose some brands with stable output, good light quality and accurate color reproduction. He feels very good about the domestic lamps he is using now, especially the light quality is very good, and the reflection of the skin texture of the characters is particularly good.

2. Light consumption, that is, the angle of light distribution and the level of illumination, directly determines the quality and effect of the image. Whether it is a single set or multiple sets, the lighting should be carried out from the same angle, otherwise the lighting will appear very messy, and sometimes even produce contradictory light, which will destroy the overall picture and composition. In a word, lighting is a relatively high technical level for photographers.

Generally speaking, there are the following commonly used light distribution methods:

Large plane light is the most commonly used light distribution method for traditional images. Generally, you need 5-6 desk lamps, a main lamp, an auxiliary lamp, a floor lamp and a ceiling lamp, and one or two background lamps. Then take the eyes of the subject as the test standard, so that all the tested lamps reach the same value. This light distribution method makes the image light softer, the exposure is more uniform everywhere, and the image is beautiful.

Function: remove eye bags, eliminate the shadow of nasal groove, and have a beautiful image.

Triangular light, the main light is located 45 degrees above the subject, and the camera is aimed at the eyes. Other auxiliary light sources and light ratio control are slightly weaker than the main light. In this way, a triangle will appear on the cheeks on both sides of the nose table, which can straighten the bridge of the nose.

Function: Straighten the bridge of the nose.

In the shadow of the sun, the main light is located 45 degrees above the side of the subject, with the bridge of the nose as the boundary. One side is bright and the other side is dark. This way of light distribution is more conducive to depicting people's mood. If the main light is directly above, adjust it slightly, and the projection of the bridge of the nose will appear on the other side of the cheek, making the bridge of the nose look strong and the eyes strong.

Function: make the bridge of the nose straight and the eyes bright.

Decorative lights, the light level is generally in the diagonal position of the main light, mainly to control the light ratio and change the color of the whole image. Lighting should be more difficult to separate people from the background and highlight the silhouette light. This can not only enrich the picture, but also highlight the sense of hierarchy. Without this kind of light, the film will be a bit lifeless and the characters will be lifeless.

Function: brighten hair, shadow dermatoglyphics, strong texture and strong three-dimensional sense of characters.
