[QUOTE="WayneF, post: 405251, member: 12496"] White for portraits of people, without doubt. The silver has uneven hot spots, but can help small flashes needing greater reflectance, and can be good for furry pets that you want to shine. The white nylon material reflects about twice what can pass through. The black cover simply absorbs and prevents that rear spill, it does not change the reflected light in any way. You want them "close as possible" anyway (3 to 5 feet), to be relatively large and soft. The black cover can't be used for shoot through of course, which will spill back about twice more than passes through. Normally that is not good, but you'd use shoot through when you need it closer than reflected can go... like 12 or 18 inches. In which case, the power needed is not much concern, and that inverse square law of that close distance overwhelms the relatively far distance to the room walls and back (several feet) so then the spill is not critically important. Shoot through normally has a center hot spot, you'd feather it off a bit to the side.
