It's really pretty simple, as far as POV-Ray is concerned: While classic 
image formats essentially use integer values to represent colors, 
capping them at 100%, HDRI formats such as OpenEXR use floating-point 
values instead, enabling them to represent color values as high as e.g. 
6,550,400% (in the case of OpenEXR).
