191Optional Flash Units
4 C: Choose the flash control mode.
Choose the flash control mode and
flash level for the master flash and the
flash units in each group:
TTL: i-TTL flash control.
qA: Auto aperture (available only
with compatible flash units; note
that the built-in flash and SB-500 are not compatible with
auto aperture).
M: Choose the flash level manually.
– – (off): The units do not fire and the flash level can not be
adjusted.
Choose a channel for the master flash. If the remote flash
units include an SB-500, you must choose channel 3, but
otherwise you can choose any channel between 1 and 4.
5 f: Set the channel.
Set the remote flash units to the channel selected in Step 4.
6 f: Group the remote flash units.
Choose a group (A or B) for each remote flash unit. Although
there is no limit on the number of remote flash units that may
be used, the practical maximum is three per group. With
more than this number, the light emitted by the remote flash
units will interfere with performance.
