Quote - One of the biggest problems, apart from trying to zoom in on small details, is that the Poser cams are locked on the 0 0 0 coordinates (other than the Dolly cam), so once you do get close to something way off-center, you can't rotate around it properly because the camera always wants to point at the center of the universe.

To get the Main or Aux camera to orbit a prop, rather than the 0 0 0  point, zero its x and y translations, zero all its rotations, Memorize it (Alt+Ctrl+H), parent it to the prop, then use Restore Camera (Shift+Ctrl+H). The camera will now orbit the origin of the prop. All the zeroing is not strictly necessary, but it stops the camera getting lost in space.
