Am I the only one who finds media utterly incomprehensible? I want to make a
glow effect, with a bright center and a dimmer exterior. So far, I've only
succeeded in making a dark circle. What am I doing wrong?

#include "colors.inc"
#include "skies.inc"
sky_sphere {S_Cloud1}
fog {distance 250
color rgbf<1,1,1,1>
fog_type 2
fog_offset -1
fog_alt 15}
camera {location <15,5,0>
look_at <0,3,0>}
light_source {<15,5,0> color White}
plane {y,0 pigment {Tan}}
sphere { <-2,2,0>, 1
pigment { color rgbf<1, 1, 1, .9> }
finish { ambient 0 diffuse 0 }
interior {

samples 1, 10

color_map {
[0.0 color rgb <0, 0, 0>]
