5. VERSATILE METERING MODES
The T90 is the world’s first camera to have all
three metering distribution patterns, i.e. center-
weighted average metering, partial metering,
and spot metering, built into one camera and
used by switching among the three patterns.
Multi-spot metering is also possible with a spe
cial button. In addition, the spot metering mode
has a memory function (approx. 30 secs) and
the AE lock mechanism comes on in both the
partial and spot metering modes when the shut
ter button is pressed down halfway. Exposure
compensation includes two methods: the expo
sure compensation index, which increments by
1 /3-steps, and the H/S control by 1 /2-step incre
ments. H/S control helps reproduce black and
white faithfully.
