Alan... thanks for the quick response. I guess I should have checked Wiki! Actually, I get your examples of EV. I still need a couple more answers... "After all that... here's the question(s)... in reality, I'm changing EV? Is that right? or am I changing shutter speed AND EV? Is it a compounded move? or can the two be separated... EV and Shutter speed?"
"BUT, in MANUAL mode, the EV is separate. What is it that the EV does when not changing shutter speed or aperture? Computer wizardry and magic? Does it add more noise?"
So, then in this case is the exposure compensation different than EV?
