I don't quite understand.  See attached image with internal focal blur for
comparison.

I used

      pigment { 
        function { min(1, f_r(x, y, z)) }
        color_map {
          [0 rgb 0][1 rgb 1]
        }   
        scale 36      
        translate Cam_Location
      } 

which is of course not really correct, but it does hardly make a
difference in this case.
