I had purchased a white background a while back and was not happy with the pictures I took with it. I recently tried something new and to my surprise, it worked. I have 2 alien bee 800 behind the subject shooting through shoot through umbrellas pointing at the white background. To the subjects left is a 580exii bouncing in an enclosed (creative lighting) umbrella. To the subjects right is a silver reflector. The room has a white ceiling and light colored walls and is not that big so the light bouncing off the backdrop diffused all over the room giving me my desired look.
