The Glow 20 degree honeycomb grid is a powerful tool in the arsenal of the artificial lighting photographer. By covering the aperture of the reflector with the disk, you gain more control of a light source's beam, and it feathers the hard light for an attractive shadow. This strong directionality can be used to add high key depth for fashion images, and emphasis on the model facial structure as well as the eyes, lips, nose and chin. The narrow 20 degree spotlight glows with more defined borders of shadow falloff, virtually eliminating spill from the rest of the body and the background. The disk simply clips on to the perimeter of the reflector rim for a secure perfect fit.
