What is the light and shadow distribution along the light?

The distribution of light and shadow along the light is bright before and dark after.

Guang Shun:

A simple understanding, that is, we often say positive light, is the light from the photographer's background to the subject. The visual effect brought by smoothing will make the photo effect more uniform, the contrast between light and shade of the whole picture will be small, and the photo will appear more dull and lack of layering.

So in landscape photography, smooth light is not ideal light.

However, smoothing also has an advantage, because the shot scene will not be disturbed by color temperature and color change, which means that the problem of color crosstalk is not easy to occur. In this way, the color of the photo will be brighter and the saturation will be higher.

In addition, when shooting portraits, Guang Shun has a good effect, especially when shooting beautiful portraits, Guang Shun can shoot more delicate and smooth details, and in addition, he can get better colors in the reflection and performance of skin color.

At the same time, the application of smooth light can cover up facial textures and spots when shooting the theme of portraits of the elderly. Including when we want to remake some video materials and photos. Good results can also be obtained by using smooth light.

The photographer's back to the sun, that is, the light from the back of the camera, is also called shun guang. Because all parts of the subject are bathed in direct light, there is light everywhere in the part facing the camera, and the result is an image without tone levels. It may not look good to pat your face with positive light, especially with high positive light.

Shun light is the most commonly used light for beginners of photography, because under shun light, the shadow of the subject is usually covered, and then the contrast between the shadow and the light receiving surface is formed, which greatly reduces the difficulty of shooting.

In smooth light, it can well express the color and shape of objects, giving people the feeling of bright sunshine.

The biggest feature of frontal light is that the subject receives light evenly and the color is really saturated, but it lacks a sense of space and three-dimensionality, which is not conducive to the realization of the subject's sense of body. In addition, the smooth light also makes the brightness of the subject change little, which is easy to produce gray tone. Smooth light is often used to shoot high-profile works.

Smooth light is often used as auxiliary light in portrait photography. In architectural photography, streamer is a taboo light because of its lack of three-dimensional sense.
