amaran Ace 30 Degree Light Control Grid

Thirty degrees is a narrow beam by softbox standards, and that is the point: this grid is for when the Ace is doing an accent, a hair light, or a background pop rather than a key. It stops light reaching anything you did not aim it at.

It fits amaran's Ace series and costs less than a coffee round, which makes it the easiest control to keep in the bag alongside the fixture.
