        As you said, your idea is the same as the "P+" one I proposed.  
My reader shows that message before this one though... so I'm just 
clarifying.

        The "Av+" mode would let you override all of that in case you ran 
out of metering range, the stop-down wasn't accurate due to blacking 
center, etc.
