Direction and method of smooth light distribution in portrait photography

Lead: In this article, let's talk about a light type commonly used in spring and summer shooting: high-pitched smooth light. High-profile smooth lighting is a light distribution form suitable for spring and summer shooting, which can be used in almost any clothing texture.

Direction and method of smooth light distribution in portrait photography;

First, the basic characteristics of the tweeter fairing

Guang Shun is also known as? Zhengguang? , refers to the projection direction and shooting direction is roughly the same light. When the light is smooth, the subject is evenly illuminated, the shadow of the character is blocked by the character itself, and the tone is softer. It is easy to photograph the texture of the object surface and restore the color well along the light. This kind of light can show a comfortable environment and atmosphere, and at the same time, it can completely depict the details of the characters, such as delicate skin and makeup.

A high-profile and stable infrastructure can be illustrated by the following schematic diagram. All kinds of specific application methods are around this basic structure:

Smooth use of high-pitched light

High-profile smooth lighting gives people a bright, pure, relaxed and lively feeling. According to the different performance content, the emotional color conveyed by the smooth picture will be different. Generally speaking, the quiet, elegant and clean images involved in landscape photography and commercial photography are mostly soft, uniform and bright.

Sunlight shooting is the basic form of photography and has its irreplaceable advantages. For example, shooting with the blue sky or green vegetation as the background will make the colors in the photo look clear and bright. Because the amount of light entering is sufficient and smooth, the background can be vivid.

Although streamer is easy to master, there are also some problems that need special attention: when the subject is evenly illuminated and the shadow is projected on the invisible back, the photos taken at this time are often difficult to distinguish between primary and secondary, lack of spatial depth, and the three-dimensional sense and spatial layering of the object are poor. At the same time, it leads to the lack of light and shade changes in the colors in the picture, and the photos appear plain and straightforward.

Therefore, in order to make up for the shortcomings that the streamer can't express the space well and the foreground and background are easy to overlap, the darker subject can be matched with the bright background, or the bright subject can be matched with the dark background to form a contrast, so as to enhance the expressive force of the image. In addition, we can also use the depth of field effect of the lens to create the relationship between reality and reality, or use the brightness difference caused by the projection of the front and rear scenes to solve the problem of insufficient depth of the scene under light.

1. Outdoor light consumption

When dealing with outdoor light, sometimes weak light is used as auxiliary light, but if the outdoor light is too strong, we should try to reduce the influence of light by adjusting the camera.

Measuring light

High-profile and smooth shooting, all the objects will be clearly displayed in front of your eyes. Exposure control is very easy. For digital SLR cameras, the ideal exposure effect can be obtained by using average photometry to shoot scenes in a smooth environment.

Secondly, the indoor artificial light source emits smooth light with high brightness

In the studio, room lighting is used to create a smooth atmosphere. The common lighting types are as follows.

1, play straight

Use a high-power flash in front of a person's side. Light is not only used to illuminate people, but also to consider the background. This light-colored pattern is more suitable for light-colored clothes with simple outline. The approximate light ratio is 1: 2.5. Note: the dark parts of the characters need to be filled with reflectors.

2, soft light side light is smooth

While creating a weak backlight in the shed, adding soft side light can well express the simplicity of space and is suitable for clothes with simple lines and styles. The front-rear light ratio is controlled at 1: 1.5. Note: To modify the details of the model's face light, you can place a light absorbing plate in the dark and add shadows to emphasize the facial texture.

3. The small light is brighter than the side light.

This light weight is more suitable for clothes that need to emphasize texture, such as suits. The light on the front is not easy to cast a shadow on the fabric, which makes the clothing look flat and atmospheric. The approximate light ratio is 1: 2.5. Note: the shadow in the dark is very small, and there is basically no need to fill the light.

4. The big light is more diffuse than the front light.

This light pattern is more suitable for clothes with large color blocks and simple lines. The front-to-back light ratio is about 1: 1.5. Note: The diffuse soft light in the back is similar to the main light in the front. Pay attention to the indicators added before and after metering, and the dark part does not need to be filled with reflector.

5, the minimum light ratio side light mixed diffuse light.

This light weight is more suitable for clothes with bright colors and simple tailoring. The light ratio is 1: 1.5. Note: Simply using the front light can easily leave a deep shadow on the background, which does not match the light texture of spring and summer clothes. At this time, it is necessary to add diffuse soft light to weaken the shadow.

Third, diffuse soft light to shoot natural light

Shooting in the daytime can produce clear and vivid effects. But if the sun is too high when shooting, it will be dazzling, and the subject hair weaving will cast a shadow on his face, which is not conducive to shooting. But when shooting, the altitude angle of the sun is about 35? It will be very convenient to shoot at this time.
