Well, I did the same and the apparent depth of the surface doesn't change
at all. All the images render identically no matter what value of 'Size' you
specify here:
#declare Size=1;
#debug concat("Size=",str(Size,1,0),"\n")
camera { location -z*4*Size look_at 0 angle 35 }
light_source { <100,200,-150>*Size, 1 }
sphere
{ 0,Size
pigment { rgb x } finish { specular .5 }
normal { bumps .5 scale .1*Size }
}
