The Interfit STR208 Strobies Pro-Flash Snoot Kit is designed for use with the Pro-Flash unit. Snoots greatly reduces and controls the spread of light from your flash and are used to direct the beam of light and highlight certain areas in your scene, while limiting the spill of light on the rest of your image. Limit the spill of light even more with the included honeycomb grid. Honeycombs are used to narrow down the spread of light by channeling the light into a defined beam. This kit includes two snoots, one conical and one cylindrical. Both will limit the light spread to a tight spot. The only difference is that a conical snoot gives you slightly sharper shadows than a cylindrical snoot, due to the direct path that the light takes from the flash to the subject.
