(False perspective)

Not wanting to be a smartass, just a real question I asked myself when watching the Hobbit: how could they make false perspective when shooting in 3D? I remember some behind the scene footage of LOTR and I found very interesting to use that old trick of forced perspective. But this can't work when filmed in 3D because the trick is revealed. Maybe forced perspective shots were post "3Dfied" or something.

I could be wrong, but I remember that being a problem with The Hobbit. They couldn't use false perspective, and so they had to bluescreen everything.
