The Chimera Medium Super Pro Plus is designed for use with a strobe. With fabric not intended for the heat of a continuous light, the Medium Super Pro Plus with white interior is ideal for work where maximum softening of flash is desired. The light quality from this softbox will be softer than that produced by a Super Pro Plus with silver interior.
The "Plus" designation of this softbox means the front face of the softbox is removable. Chimera makes different strengths of diffusion material for front face applications. The softbox comes with a one stop diffuser, but a 1/2 or 1/4 grid cloth can be purchased separately. These would allow more light transmission and help to make the light more specular, or "less soft."
