The Big Bounce redirects and softens the light in the same manner as the UltraSoft, with even softer results since it is roughly 20 times the size of the flash head itself. For use where a softer lighting effect is more important than "pocket size" portability. It is ideal for close-ups, portraits, etc. Fits the same wide range of flashes as other LumiQuest models. Bundle includes an UltraStrap, the most secure non adhesive mounting strap in the industry.
