The 3-Piece Flash Diffuser Set for Nissin Di866 MkII from Movo Photo combines a standard diffusion cap, a warming diffusion cap, and a fluorescent-correct diffusion cap in a convenient set, so you can be prepared for a variety of shooting circumstances. The white diffuser softens strobe output to reduce harshness and shadows. The gold diffuser provides the same type of diffusion as the white cap, and adds a warming color for enhanced flesh tones for portraits. The green cap can be used to match existing fluorescent lighting, or for a creative wash of color. The caps are designed to fit directly on the front of the Nissin Di866 MkII strobe unit without the need for touch-fastener tabs or other mounting connectors.
