I posted the pic in p.b.i.:

Forgive my grammar, I'm not quite sure how else to word it...
Shouldn't there not be shadows on the plane?  And shouldn't the background
be flat grey (no light attenuation)?

#include "colors.inc"   // Standard Color definitions
#include "golds.inc"

light_source {
  <0,2,-1>*8
  color White
}

sphere {
 0, 20
 texture {
  pigment { rgb 0.5 }
  finish { ambient 1.0 }
 }
 hollow
}

plane {
 y, 0
 texture {
  pigment { rgb 0.5 }
  finish { ambient 1.0 }
 }
}

#default {
 texture { T_Gold_5A }
}

sphere {
 y*1, 1
}

camera {
 location <3, 3, -3>*0.7
 look_at y*1
}

There are shadows since the diffuse finish is the default value of 0.6 and
the background is not plain flat since the angle towards the light source
changes and therefore the brightness (also due to the diffuse finish).

This all has nothing to do with 3.5 beta of course.

My apologies for the wrong group posting.  I had been able to create a flat
colored planes in previous versions (or think I remember doing that).  Thank
you for humoring me.

Just add a diffuse 0 in your finish statement and you'll get no
shadows.
