Ive tried to use the huge octa as a backdrop before but always got so much flare it completely washed the contrast. Even when I exposed the octa just below completely blown out, I still couldnt get the contrast you have here. Any tips?
Hm. It could be a lens issue? Some lenses do not handle direct light as well as others. I've only shot this way with the 70-200 2.8, and it does just fine. I turn the front light (which in my case was the large octa) off, and then dial the back light down or up until I get just the amount of wrap I'm looking for. Then I just turn on my front light, dial in the right power setting, and shoot away.
