It has been my thought that Luminance was the light reflected from a given subject, Illuminance was the light on the subject?

Yes, that is what I am concluding also. But, contrary to most photo essays, I see no reason to care about the light on the subject.  I really, really care, though, what my camera's sensor is sensing.

That was a significant reason why I decided on a MFT camera with a live view EVF instead of a DSLR with an OVF a couple of years ago.  Of course there were other reasons, especially the ability to use good small diameter, short lenses.

Thanks,
