Can portrait photography change the skin color of a model by changing the light level?

In portrait photography, the light level is determined by the positions of the photographer, the subject and the light source.

The light levels commonly used in portrait shooting are smooth light, front side light, side light, side backlight, backlight and top light.

Split light is widely used in portrait photography, and it is also a light level widely used by beginners in portrait photography.

When the sun shines, the light is directly projected to the side of the subject facing the lens, so that the side of the person facing the lens is the light receiving surface, and the light is relatively uniform, with little change in light and shade, which can well represent the skin color, clothing and various details in the picture.

However, due to the direct light from the front, the picture lacks the necessary shadows, sometimes it appears peaceful and cannot express the three-dimensional sense of the five senses of the characters.

The light from the object to the left or right front of the camera is the front light.

The front side light has obvious sense of direction, which can produce good light effect and rich colors, but when the light is strong, the direct light may be partially overexposed.

When shooting with sidelight, half of the side facing the lens is illuminated and the other half is on the dark side, which can give people a strong sense of three-dimensional sense and strength, but the dark part may have no sense of hierarchy and lack of details.

The light source of side light is located at the left oblique rear or right oblique rear of the photographed object, and the side light can illuminate about one third of the body of the photographed object. This kind of light has the characteristics of side light and backlight at the same time, which can not only increase the outline of the light, but also increase the three-dimensional sense and layering of the photo.

Backlight is the light emitted from the back of the subject.

Backlight can illuminate the outline of objects and create bright outlines for people. If you shoot with backlight alone, the side facing the lens will darken due to insufficient light, so you need to cooperate with a reflector or a flash to shoot.

The top light will form a thick shadow on the eyes, nose and chin of the characters, which is not conducive to the performance of the characters, but it will also have a unique effect if used properly.
