The MilaGrid PortaGrid Flash Diffuser denser weave Grid Matrix to broaden the light source across its 6.6" width. These precision-gauge Light Conduits create a lesser volume of more highly diffused light than the BounceGrid, while the Light Gates continue to allow light to pass unobstructed towards ceiling and walls, providing reflective fill.
Additionally, the PortraGridTM adds 7 large "Ceiling Flood Gates" along the top surface to direct substantially more light towards the ceiling, causing a proportionately greater volume of ceiling-reflected light to strike the top-front of the subject.
The PortraGrid diffuser is most efficient when used with 8-10' ceilings, and at a distance of 5-12' from the subject. The results are soft, smooth transitions from highlight to shadow, with a lighting pattern more consistent with natural light, and as with all Grid Matrix diffusers, enhanced highlight smoothness and tonality, and beautifully luminous shadows.
