A ring light is a circular lighting tool commonly used in photography and videography. It provides even, diffused light that reduces shadows and highlights the subject's features. Ring lights are popular among content creators, makeup artists, and photographers for creating professional-looking images and videos. These lights typically come with adjustable brightness and color temperature settings, allowing users to customize the lighting to suit their needs. Many ring lights are designed to be mounted on a tripod or a stand, making them versatile for various shooting angles and settings.
