This mild directionality can be used to add high key depthfor fashion images, and emphasis the model facial structure as well as the eyes,lips, nose and chin. The matte black 40 degree honeycomb creates a spotlight glow with defined borders of shadow falloff, eliminates spill from the rest of the body and the background. Creative alternative uses include interesting background effects and cast shadows, colour projection and edge light. The disc simply clips onto the perimeter of the 20cm reflector rim for a secure perfect fit.
