What is the difference between
light_source { 0*x color red 1.0 green 1.0 blue 1.0 ...etc.
and
light_source{ 0*x color red 0.5 green 0.5 blue 0.5 ... or any < 1.0
for all three colors?
Does using lower but equivalent values for the three colors mean lower
intensity of light?
TIA,
Mark M. Wilson

This also means that the values can be higher than 1.0.

Absolutely. In many cases it's better to use values higher than 1.0,
especially when the light fades out in the distance like light sources do in
reality.

This I did not know! I guess I need to bone up on lighting in POV!
Thanks, folks!

Well, what I mean is I didn't know you could specify values greater than
1.0. Of course I knew that natural light DOES fade out in the
distance.... :-)

Fading light brightness is not usually specified with the color intensity
but with fade_distance. The larger the fade_distance, the brighter the light.

I have no idea who it was or when it was, but someone posted a nice lighting
macro which enables you to define lightsources by using real life values (40
watts, etc.)
