No post-processing what so ever, I never do.

Here is the relevant part of the code, with some comments.
I hope this helps.

   Veijo

box { <0,0,0>, <1,1,0.01>
   pigment { image_map { tga "eye.tga" } } // the eye photo,
      // which is a straight crop from a larger photo
   translate <-0.5,-0.5,0> scale <1.5,1,1>
      // translate to the origin, restore format to 3:2
   rotate 18.5*x translate <0,-0.09,1> } // rotate to correct
  // for the perspective as the camera isn't quite horizontal

sphere { <-0.06,-0.1,1.02> 0.03 texture { T_Gold_3C } }
   // NB. this sphere is there just for a visual effect
sphere { <-0.07,-0.145,1.18> 0.295
   // for the iris reflections
   // position and dimensions empirical
   texture { T_Glass3 } interior { I_Glass } }
// actually, these two spheres ought to be unioned
// with the photo before the corrective rotation

union {             // this does the job
   height_field {
     tga "hf2b.tga"  // a bozo height field
     smooth scale <2, 0.015, 2> }
   box { <0,-0.101,0>, <20,-0.098,15> }
    // something like this seems to be required to make the HF work
   rotate -90*x translate <-1,-1,0.7>
   pigment { rgbt <1,1,1,1> } interior { ior 1.05 }
    // the ior value is empirical, modify ad lib
   }
