spot meter modes of Olympus cameras
introduction
-
unfortunately, it does not really help you to learn what it is doing, nor how to take control of the the exposure yourself
on the other-hand, spot metering, although it takes some time to understand and master, can really make you into a much better photographer:
you can get far more accurate and consistent exposures, particularly in high contrast situations
YOU LEARN to DECIDE HOW YOU WANT a subject rendered
Olympus spot meter modes
spot meter is always the centre spot - NOT the AF selection
-
in an exposure mode that is not manual, you MUST lock the exposure, otherwise as you recompose, the exposure will vary wildly depending upon the reflective brightness of the target in the spot (in manual mode, the metering reading will change but not your exposure as you have full control over it)
normal spot meter
meters assuming the subject is an 18% gray card
if you expose according to the reading giving 0.0EV, the target will be rendered as 18% gray even if it is actually black or white - this is how camera meters work by default
HI spot meter
LO spot meter
to really learn to use the spot meter modes, learn Zone System first
