Hmm assistants you say? I think I just discovered where I have been going wrong. I need Kate Beckinsale as my photo assistant. Her magical glow will perfectly fill in shadows in all my scenes, no matter their scale. Hmm yes that's the ticket. Thanks. There is something somehow very appealing about this way to reach 15 stops dynamic range, something that I feel would be lacking were I to use a D800 instead.
I said assistants, not models
An assistant is usually some smelly, hairy, overweight dude that's hung over from the night before
As far as reflectors go, I don't ever see them going away, regardless of how much DR improves in the coming years. There's just a certain quality of light you can achieve with them, and I use them to manipulate highlights, reflections, and light volume more often than I use them for fill light.
Check out this video taken by a super high end commercial photographer. He's shooting with a Phase One P65, which does quite well at 13 stops of DR, according to DxOMark. What do you see 2:40 into the clip? That's right, a reflector chmil.
On a side note, that Phase One shutter sounds sweeet
