The diffuser softens the harsh light emitted by the flash to diminish the appearance of shadow on the subject or object being photographed. The diffusers also make the light more balanced and uniform for improved photographic results. Simply attach the diffuser to the upper part of an external flash unit to create more natural, professional-looking images. As the flash emits a dense burst of light, the diffuser spreads it out to make the subject look subtle, natural and flattering—the perfect kind of illumination for portrait or wedding photography, but also for use in portrait photography, outdoor events, fashion displays and product displays. Suitable for: NEEWER TT560 TT520 Flash Speedlite. Lightweight and easy to carry with you! Note: This product is not manufactured by Canon or Nikon. Flash is not included!
