Ring lights are used to throw an even light across the subject that appears to be coming from all directions around the camera lens. This “soft” light minimizes and smooths those unflattering shadows on the face, thereby reducing any blemishes. Ring lights also produce attractive and distinctive specular highlights in the eyes or catchlights. Therefore portrait and glamour photographers frequently use ring lights. They are also a go-to light for videography where one person is speaking to the camera. This is why many professional YouTubers often use ring lights. But these lights have come down in price as LEDs have replaced circular fluorescent tubes. They are now much more affordable and help ordinary vloggers and anyone on a video call to look great on camera.
