The Lowel Snoot for the Omni-Light reduces the beam-angle, creating a soft-edged circle of light and rotates 360° for each scenario. It requires either the Complete Barndoor Set (O120) or the Barndoor Frame (O121) for mounting. Two snoots joined by the Barndoor Frame increases this effect.
Use of a snoot will result in a small circle of light, when it is attached to the front of a light source. The size of the circle of light will be determined by the opening of the snoot, its length, and the distance of the subject. Consider them as a painter would a brush, or a sculptor would a knife, or chisel.
