I can assert that Chris *does* go for a walk from time to time, even
if only to meet fellow POVers or ride his insane home-made bike :)

I'm mildly flattered that you imagine that I could understand that.

Ordinary images store intensity percentages. You can have from 0% to 
100% intensity, with 100% being "white", anything brighter gets chopped 
off. HDRI doesn't have that limitation, it keeps more information which 
makes it useful in processing and rendering calculations even if it 
can't be displayed.
