The SoftBox III is roughly twice the size of the original Lumiquest SoftBox, thereby producing considerably softer shadows. It fits conventional flashes (Nikon, Canon, Sunpak, Vivitar, etc.).
The SoftBox enlarges and diffuses the light with the flash in the direct flash position. The light is softened and more evenly distributed as it passes through a center-weighted frosted diffuser.
Producing a narrower beam than their 1/4 Speed Grid, the 1/8 Speed Grid has a 1/8" honeycomb cell size to narrow the beam of light from your portable flash unit.
