perhaps a noob quest.
in manual, while using matrix metering, when picturing a picture.
after adjusting the aperture and the shutter speed, to balance the metering in the viewfinder, say after all the nice adjustment, I set the exposure to -2.0 EV, the metering will change again, should I readjust the metering again? (I sound a bit stupid and confused)
supposing adjusting exposure compensation is to overwrite the exposure cam choose for the pic, so after I changed the value, I just shoot right?
