What does it mean when you get a DGI glare index value of less than 0.0 ?

Hi Don,
values less than 0 doesn t make sense in principal, but are mathematical possible when you look at the equation. (log function)
It means that you consider areas with a very low luminance as a glare source or your background luminance is very high.
