Special FunctionsSpecial Functions
S/A/H (Shadow/Average/Highlight)
calculations
S/A/H exposure calculation functions cannot be used in AMBI FNo. mode,
when using the brightness difference (exposure difference calculation)
function, or when using the instrument as a simplified illuminance meter.
Average exposure
This function calculates the average of two measurement values in
memory. (This can be used with both incident-light readings and reflected-
light method.) For example, if there is a wide difference in brightness within
a composition, the meter stores the readings of two points in memory and
then calculates the average exposure value from these two values.

Press the memory button
to store the second
measurement value in
memory.
● The data panel turns off for a
moment as the value is stored
in memory. Now a second
pointer appears at the right of
the analog scale to indicate that
two values are stored in
memory.
● Up to two values can be stored
in memory at one time. If you
now take a third reading, this
value will also be displayed on
the analog scale with the
previous two values (two
memory values and the latest
measurement value).
● When there are two values
already in memory, pressing the
memory button deletes the
oldest of the two values, so that
the two newest measurement
values are stored in memory.
● If you change film speed or
shutter speed after pressing the
memory button, the stored
values are changed accordance
to the new setting. (These
changes are also reflected on
the analog scale.)
● If there is no reading on the
digital readout, or if the current
reading is out of the meter's
measurement range, pressing
the memory button does not
have any effect.
● To delete all values from
memory, turn the power off.
2
Use the up/down key
while pressing the S/A/H
button to set the meter to
“A” mode.
● Attaching a receptor for
incident-light readings
automatically sets the meter to
“A” mode. (In this case, the
meter cannot be set to S or H
mode.)
Measurement values that are
not stored in memory cannot be
used in average exposure
calculations.
1
Take two readings of a
subject (e.g. highlight and
shadow area) and store
the two measurement
values in memory.
