Post-Measurement Calculation
(1) Post- measurement calculation by
chang ing ISO sensitivity :
By changing ISO sensitivity th e
measured F-stop val ue is
automatically changed to the
appropriate one correspond ing to
the changed ISO value (Fig _ 31) .
This calculation is applicable to al/
measuring modes, both flash and
ambient light measurement.
(2) Post-measuremen t calcu lation by
changing T value :
By changing the set shutter speed
(T) the measured F-stop value is
automatically changed to the
appropriate one correspond ing to
th e changed T value (Fig _ 32).
This calculation is applicable only
for ambient light measurement in
T-priority mode.
