There are two kinds of photographic light sources () and ().

There are two common photographic light sources: natural light and artificial light. Photographic light source is one of the most important elements in photography, which directly affects the effect of photos.

Natural light refers to light from nature, such as sunlight, moonlight and starlight. Natural light is one of the most common light sources, because it can be used anytime and anywhere without any extra cost. Natural light is characterized by softness, naturalness and truthfulness, which can present very real colors and textures. However, natural light also has its limitations, such as bad weather will affect the brightness and color of light, and the shooting time is also limited by sunrise and sunset.

Artificial light refers to the light generated by lamps and other equipment, such as flashlights, LED lights, light bulbs and so on. Artificial light can be adjusted as needed, and its brightness, color and direction can be controlled. It can be used anytime and anywhere, which is very suitable for indoor shooting. The characteristics of artificial light are bright, clear and sharp, which can highlight the outline and details of the subject, but if it is not used properly, it will produce too many shadows and reflections, which will affect the effect of the photo.

To sum up, natural light and artificial light have their own advantages and disadvantages. Photographers need to choose the right light source according to the needs and conditions of shooting in order to take high-quality photos.
