The Vello 1/8" Honeycomb Grid for Portable Flash attaches to your portable flash and dramatically narrows the beam of light that's put out by your shoe-mount or handle-mount flash. The effect is a small circle of light, with the size depending on flash-to-subject distance. The grid attaches to your flash with the included touch-tab fasteners.
This 1/8" version produces a beam of light that's a few degrees narrower than the 1/4" honeycomb grid (available separately).
