	Let me rephrase without appearing to post for the sake of
posting. 

	There are semi-log functions and quatro-log functions. At
deci-log it might as well be linear. At some point they have to
pick one number range. Phong is technically as wrong as this one
but the complaints have died down. 

	As I am constantly reminded, POV is not just for folks who
understand what we are talking about with linear and log. 

	If I see anything (still having the source code but not having
screwed up my courage to the sticking point to dive into it) I
see a mixture of log(0-1), log(0-10) and no log at all. Usually a
range of numbers is in the docs.

	I will say two things about the docs. The docs are poor. The
docs are better than most programs over $500. I know of no higher
compliment for a free program. 

	As for this problem, when I try something new and it does not
work as I expected I treat it like an alpha tester. I try the
extremes first. 1000 and then .001 then go to .5. Hit the
extremes and the average. And honestly after much frustration I
usually discover I was doing something wrong in the first place. 

	There is an old trick cut by halves. In eight tries you are down
to one part in 64k. That will quickly show you where effective
changes are.
