What does the light ratio of photography mean?

The light ratio of photography refers to the ratio of light intensity used in shooting. When shooting, the brightness of light is usually uneven, which requires the photographer to adjust the combination of light intensity according to the actual situation to achieve the required picture effect. For example, when shooting a person, it is necessary to highlight his body contour, so that a high proportion of light can be used to make the silhouette of the character clearer and more vivid; When shooting scenery, it is necessary to use low-proportion light to make the whole picture more natural and true. Therefore, the light ratio of photography has become one of the key factors affecting the shooting effect.

For photographers, controlling the light ratio needs to start from many aspects. First, you can control the light intensity in the scene by choosing different lights or reflectors. Secondly, in actual shooting, the light ratio of the picture can be changed through the combination of scene composition and camera exposure. For example, by adjusting the exposure time and aperture size, the brightness of some places in the picture can be higher, and the emphasis in composition can be emphasized, thus controlling the light ratio. In short, if you want to master the light ratio in photography, you need to have certain photography skills and rich practical experience.

What effect does light ratio have on photos?

Light ratio has a great influence on photos. In the same scene, different light ratios can present completely different picture effects. For example, a high proportion of light can produce a strong contrast between light and shade, making the subject in the picture more prominent; A low proportion of light can make the whole picture softer and more natural. Therefore, photographers need to choose the appropriate light ratio according to the theme and picture effect they want to express, and use the light ratio control skills flexibly to create more excellent photographic works.
