I posted a few thoughts on using depth maps with Commotion Pro recently and I think similar things can be done in After Effects or Photoshop. Quite a while someone wrote up something specifically for Photoshop were you could use curves to do the same thing (but I haven't been able to find that posting again). All in all, the G-Buffers are quite useful.
