Hello, ray tracers.  I am a newbie.  I am the newest newbie that there ever
was--my first ray tracing was today!  I figured I would try my hand at
ray-tracing with a practical assignment.  One of my clients (I am a
programmer) needs new buttons for his web site.  I have made the base for a
lovely button, but the background is not coming up white.

How do I make the background come out white?  I, like any newbie, figured a
white light on a white plane would come out white!  Please enlighten me and
my image.

I have included my code below.

Thanks,
Hershel

#include "colors.inc"

#declare Cam1 = camera { location<-2,0,0>
                         look_at <0,0,0>}
#declare Cam3 = camera { location<0,2,-8>
                         look_at <0,1,0>}
camera{Cam3}

light_source{<-2,15,-15> color White}

blob {
    threshold .65
    cylinder { <0,0,0>, <4,0,0>, 1, 1 }
    cylinder { <0,1,0>, <4,1,0>, 1, 1 }
    cylinder { <0,.5,0>, <4,.5,0>, 1, 1 }
    pigment { Blue }
    finish { phong 1 }
  }
plane {<0,0,-1>, .25
       pigment {color White}
      }
