The FF 5 x 6.5' HC Fast Frame Scrim Diffuser with Grid from Intellytech is for illuminating a large subject or area with light fixtures or natural light. With the Fast Frame system there's no assembly of softboxes or concern about speed rings dedicated to specific lights. The metal frame locks into place in seconds and can be supported upright or overhead with optional light stands and grip heads. You can pump light through the diffusion cloth for soft lighting or fill light. The cloth is often used with the kit's honeycomb grid to direct the light source and allow selective lighting. Another option is overhead use, like a butterfly, to tame the contrast of harsh light or the sun. It all fits in the included carrying bag.
