Abstract

A system and method for providing lighting effects comprises an arrangement of low power lights mounted on a frame having an opening through which a camera can protrude. In one embodiment, light-emitting diodes (LEDs) or light-emitting crystals (LECs) are arranged on the frame in a pattern of concentric circles, with the frame being ring-shaped and having a circular opening through which a camera can protrude, and a mounting bracket and assembly for attaching the frame to a camera. The LEDs or LECs may be electronically controllable so as to provide differing intensity levels, either collectively, individually, or in designated groups, and may be strobed, dimmed or otherwise controlled according to manually selected or programmable patterns.
