Ring lights are used by camera buffs for macro-photography. It's an excellent way to light the subject of the photograph from the same angle of perspective as the camera lens. This is important for avoiding shadows. It's also desirable to have a softer light than a regular camera flash.
This DIY project inexpensively builds a circle of LED light units into a form that can be easily screwed onto the front of a camera lens.
