What does photographic light ratio mean?

The light ratio in photography refers to the brightness ratio between the brightest and darkest parts on the subject. In the process of shooting, the correct light ratio distribution is very important because it helps to enhance the details and visual effects of the image. If the light ratio is incorrect, there may be insufficient brightness or overexposure in the image. Therefore, finding the right light ratio in shooting is one of the necessary skills for photographers.

There are many ways to master the photographic light ratio, and they are different with the change of shooting environment. In the natural light environment, the best light ratio can be obtained by properly choosing the time and position. At the same time, the use of lights and other lighting equipment can enhance the light ratio of images in low light environment, thus maintaining the clarity and details of high-quality images. Therefore, whether shooting indoors or outdoors, it is necessary to understand and master the lighting skills under different light ratios.

it should be noted that the appropriate distribution of photographic light ratio should be based on the theme and purpose. For example, properly increasing the light ratio can highlight the outline of a person when shooting a portrait, while the highlight ratio is more suitable for capturing the moment of violent action. Therefore, for different themes and environments, it is necessary to consider the light ratio factors to ensure that the final image quality and effect can meet expectations.
