Perhaps I'm wrong, but the typical color mapping that is found in most 
renderers seems to be a much more simple thing and to belong to the "global 
operators" class described in the Wikipedia article. It's even implemented 
in free renderers like Indigo and Kerkythea, so I tend to assume that the 
basics are well known to CG programmers. In any case, the exposure control 
from Megapov would be a good start already.
