The depth of the Quartz Plus is ideal for an open-face light. It is shallower than the Daylight Plus Bank designed for Fresnel Lights.
Use this box for the softest light possible. The "Plus" designation means the face of the box is removable. Chimera makes different strengths of diffusion material for front face applications. This softbox comes with a one stop diffusion cloth, and additional 1/2 and 1/4 grid cloths. Substituting a half or quarter difusion, or taking out the interior baffle will result in more contrast, slightly more light transmission, and less softening of the light.
Recessed face makes the soft source more directional, and enables addition of a honeycomb grid, soft fabric grid or louvers.
