[OM] Scanner DOF

[Wayne Harridge]

Probably a question for Dr Focus.

I'm wanting to scan some 3D objects on a flatbed and wondering how much
depth of field I need.  Assuming the resultant print is "life size" (i.e.
~A4) what vale of circle-of-confusion should I be using.  This should be
related to the resolution of the human eye at a normal viewing distance I
think - so what is that value ?
