Adding a normal is easy to add and gives you a lot of options to work
with. Any pattern that works as a pigment also works within a normal
statement. I tested this example with the .png you sent me and it
effectively removed the problem you were seeing (although I did go
a bit overboard with it - YMMV).

See below for a simple example -

 height_field
 {
   png  "devils_tower_WY.png"
   smooth
   translate <-.5, 0, -.5>

  scale <15,1,15>
 
   pigment { White }
     normal { granite 1 scale .5 }

 }
