This 8 x 8' Silent Gridcloth Lite Fabric from Matthews will fit any same brand frame. It can also be used on frames from other brands. The 8 x 8' butterflies measure approximately 7.8 x 7.8'.
Matthews fabrics are tested for even light distribution in a black chamber with an incandescent light source at one end, with the fabric positioned two thirds of the way between the source and the digital light meter. This cloth provides slight diffusion and minimal light loss.
Best suited for outdoor video, or cinematography, when the rustling sound of fabric in the wind is unacceptable.
For heavy softening of sunlight, or studio fixture output.
