How does bouncing the light soften the shadow?
Essentially, the larger the light source, the “softer” the shadow, given the same lighting source to subject distance. The larger light source makes the transition between the area which is fully illuminated and the area in deep shadow more gradual or “softer”. By using a LumiQuest® device, or any bounce surface for that matter, you are making that surface the new light source, thereby increasing the size of the light source.
