Profoto アンブレラディフューザー (ラージ)

Popped this over a lastolite umbrella and the change in light quality was immediate—much more even and flattering for headshots. The elastic cord holds it snugly without any sagging.

The way this diffuser stretches over the umbrella is incredibly smooth and the light it throws is noticeably softer than just the umbrella alone.

I was worried the fabric might feel cheap, but it's surprisingly sturdy and the velcro closure holds tight even when the umbrella is fully opened. Transformed my regular white umbrella into a much softer key light in seconds.
