For a realistic effect that helps hint at your scene's dimensions, set 
the "aperture" parameter to a value corresponding to about 5mm - a 
diameter of a human pupil - in your scene. E.g. if your scene uses 1 
unit = 1", set aperture to 5/25.4 = 0.197.

Similarly, when trying to simulate a photographic camera, "aperture" 
should be set to a value corresponding to whatever physical diameter the 
camera's aperture is supposedly set to (or, more precisely, /appears/ to 
be set to when looking into the camera lens).
