The LumiQuest Snoot XTR is a two piece kit that is designed to isolate the light to a very specific area. When used alone, the Snoot will isolate the light to approximately 10°. By inserting the telescoping extender with "hash marks", the photographer will consistently isolate the light to an area of 5° or less. The Snoot XTR is a great accessory in the camera bag for use when needing to illuminate a specific area of a scene with little or no effect on the surrounding area. In addition, it works great in the studio or on location as a hair or accent light.
