The ring light is a simple lighting tool that is commonly used for beauty shots, portraits, and macro photography. It features a number of small bulbs forming a circle or just one circular fluorescent bulb. When used in photography, it creates an attractive catch light on a subject’s eyes. At the same time, it emits even, diffused lighting, similar to a softbox, that helps eliminate shadows. You can position this light in front of the subject, with the camera situated in the middle of the ring. Smaller ring lights can also be mounted on the camera lens for macro photography.
