The Manfrotto TriGrip 2-Stop Diffuser is an ideal light shaping tool for managing contrast or enhancing your portraits with creative fill-light. This model is a translucent diffuser that softens harsh light passing through it while absorbing 2 stops of brightness. It's especially valuable for eliminating deep shadows cast by strong sources such as the sun.
The TriGrip replaces the traditional round reflector with a unique triangular design incorporating a built-in handle. This comfortable grip allows for easy manipulation of the panel without a stand or support and is especially useful when you are working alone.
The triangular shape features a rigid grip handle at one corner. It collapses down to 1/3 its open size.
