Flash Bounce Diffuser Softer Light Effects White Cap Diffuser for Canon 580ex II Yongnuo YN-565EX YN-568EX YN560 III YN-560EX Meike MK910 Fluorescent Bounce Dome Diffuser for Canon Speedlite Canon 580ex II Yongnuo YN-565EX YN-568EX YN560 III YN-560EX Meike MK910 . The Flash Soft Light Diffuser will diffuse the light output of the flash, producing softer shadows and a soft, more natural glow rather than the harsher effect when using a direct flash. The diffuser also helps to provide even coverage across the entire frame which is especially useful for wide-angle shooting. Since each Bounce Dome is custom made for the flash, it slips on and off without the need for touch fastener tabs. Additionally, the diffuser can be used outdoors to lend warmth to skin tones in open shade or to match the light balance of a sunset or sunrise portrait.
