The Rogue Large Diffusion Panel requires a Rogue Large Positionable Reflector, sold separately. The Diffusion Panel attaches to the face of the Large Reflector, creating a low-profile soft box. Ideally suited for location photographers using speed lights, Rogue FlashBender Diffusion Attachments provide additional light control for users of the Rogue FlashBender Reflectors. The innovative Diffusion Panel design produces an even light across its surface that softens light bounced off a Rogue FlashBender Reflector (sold separately).
