OK Brace yourself! LOL

I don't know why you make this so hard. Read the scene and either adjust the light to fit the range, or chose those elements to sacrifice to the photon gods. By calibrating the meter, camera and lens, you will have accurate info on which to base your choice.

Then it is all about how much work do you want to go through to get the "best" picture. See the obsessing thread.
