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.
