I did just that... replaced the three lights (which LPub creates, I assume?) and
tried the code as shown on that posting. It seems way way too bright. Now, I
am trying to use the radiosity file radio_1.inc. It contains this line:
ambient_light rgb <0, 0, 0>
Could that be causing some of my grief? Do your BFD renders use radiosity?
The biggest problem seems to be in creating the white color that the ladder is
using. It seems to get way over exposed, while at the same time the red of the
truck body is either too hot, or so dark it doesn't look red any more. And yet,
the whole time the white is nearly blended into the background.

Ah yes. Now I see... kind of. ;)
I like the way you described the relationship between the positive and negative
numbers and their effect on the model. I find the POV instructional material is
big on explaining things in very techie language, but very small on giving
actual working examples, or simple plain English explanations.

I know there's a joke in there, but I'm not sure what it is. :)
Thanks again! I'm off to try more renders.
