Yes, that is what I meant-- and you explain it better than I did :-;

I do see the reason for rad brightness 1.0 now; but it's the turning down of the
sky brightness that puzzles me.
Still assuming a low-dynamic-range setup, not HDR: If I use a sky photo of
clouds that looks nice-- set to emission 1.0, and which might actually appear in
the rendered scene-- turning down its brightness (i.e., emission value) will
cause it to have a 'dull' visual look in the render (what was once full white
now being a somewhat darker gray, for instance.) While that may indeed 'balance'
the radiosity lighting as far as color-clipping of object surfaces goes, the
visual appearance of the 'sky' itself is now dull. (That was my reasoning for
making two identical photo-mapped sky spheres-- where the *visible* sky is still
at emission 1.0)
So maybe my two spheres simply don't have the proper no_reflection tags (or etc)
in the right places? You may have alluded to this earlier; but which setting to
use where is still a little mysterious (so that all the rad 'numbers' again work
correctly behind-the-scenes.) Sorry to keep asking these odd questions; there's
only a *little* bit of mystery remaining ;-)
