CENTER-WEIGHTED AVERAGE LIGHT METERING
The OM-3Ti uses center-weighted average light metering
for its basic light metering system. This system
emphasizes measurement of brightness in the center of
the screen, rather than averaging measurement of the
brightness of the entire screen. Thus, the main subject in
the center is unlikely to be insufficiently exposed, even
when the background is too bright or too dark. This
metering system thereby does an excellent job of
handling most ordinary shooting situations — such as
situations when front-lighting and contrast isn't too strong.
Since the OM-3Ti has a light-receiving element in an
ideal position at the bottom of the mirror box, the amount
of light that arrives at the light-receiving element doesn't
change even when the focusing screen is replaced. For
this reason, the OM-3Ti achieves correct light metering
with all focusing screens. Additionally, there is no
adverse effect from rear incidence light through the
eyepiece.
