The Norman 810722 Barndoor Blind attaches to all Norman studio flash heads and it is generally used for background illumination and wide angle diffused bare bulb lighting.
The frosted Pyrex™ cylindrical dome diffuses and causes the flashtube and modeling lamp to be in alignment for accurate previewing. The two barndoor leaves enable the light to be feathered to create the desired effect.
