Abstract
Abstract Apparatus for use with a camera and flash unit to provide diffused light, including a support frame for holding a flash unit so it emits light upwardly, and for holding a reflector screen above the flash unit and facing forwardly and downwardly to reflect light from the flash unit in a largely forward direction. The reflector screen includes a sheet of flexible reflective material and a resilient wire reflector frame for holding the reflective sheet taut and for mounting it on the support frame.
