No doubt! ;-) It can't be easy, trying to reconcile what might be considered an
'oil and water mix' of different philosophies and requests.

Yes, I do see the need for that--having to work by necessity with raw linear
lighting values, AFAIU, and over a *very* large numerical range. (In fact, it's
these particular issues that are driving me toward buying a new high-end camera,
to start experimenting with HDRI in POV-Ray.)
