The Sunbounce system consists of a collapsible aluminium frame that can be easily assembled and combined with different reflecting, light-reducing, or light-absorbing screens to take full advantage of any kind of light, hard or soft, natural or artificial. This Pro Black/Soft White Screen (4 x 6') from Sunbounce is the reversible black/soft white screen for the system. The black side is used to block light, the soft white side reflects a soft diffused light. Frame is not included.
