Flash diffuser for Yongnuo YN680 flashes will diffuse the light output of the flash, producing softer shadows and a softer, more natural glow rather than the harsher effect when using a direct flash. The diffuser provides even coverage across the entire frame, and is ideal for use with lenses from 15mm to 200mm in 35mm format (and equal in other formats as well).
The Bounce Dome Diffuser effectively diffuses light from the flash and softens shadows thus producing more natural look and feel to the photos compared to using only flash. By using the diffuser the light from the flash provides even spread light coverage, making it ideal for use with wide and ultra-wide angle lens. It's easy and quick to attach by simple slide onto the flash head.This Yongnuo flash diffuser simply slides onto and off the flash with custom fitting, without the need for touch fastener tabs.
The purpose of the diffuser dome is to give an effect known as “bare bulb” from flashguns where the reflector cannot be taken off to expose the flash-tube. The reason for bare bulb is to spread light around the whole environment as well as having a proportion going forward to light the subject directly. That which bounces off the walls and ceilings then serves to fill in the shadows, and lighten them. The shadows are still sharp, not softened, but are notably less inky dark than direct flash alone.
