You could call it 'Nancy', and I would not mind

No, but my friend, Nancy, might.  (On the other hand she might be honoured to have an important physical variable named after her!)

Simon, you've been through all of this stuff before so it is not important to you.  But consistent terminology sure makes life a lot easier for beginning photogs like me.  So I have to use vocabulary which is internally consistent and (hopefully) is consistent with generally accepted SI terminology.

I prefer not to use Dynamic Range to describe the variation in "brightness" when looking through a viewfinder since DR is used for so many other variables -- including all the fluff that manufacturers use to describe their wonderful megapixel sensors (to uninformed consumers).

But I do like the levity that you add to a life/death matter!!!
