Controlling Remote Flash Units

Remote flash units can be controlled via optical signals from an optional flash unit mounted on the camera accessory shoe and functioning as a master flash (optical AWL). For information on compatible flash units, see “Features Available with CLS-Compatible Flash Units” (0 Features Available with CLS-Compatible Flash Units).

If the flash unit in question is an SB‑500, settings can be adjusted from the camera. For more information, see “Using Optical AWL with the SB‑500” (0 Using Optical AWL with the SB‑500). See the documentation provided with the flash units for more information.
Settings for other flash units must be adjusted using flash unit controls. For more information, see the documentation provided with the flash unit in question.

Using Optical AWL with the SB‑500

Mount the flash unit on the camera accessory shoe. Select [Optical AWL] for [Flash control] > [Wireless flash options] in the photo shooting menu and take pictures using group flash control. Settings for the flash units in each group can be adjusted separately.

C: Highlight [Group flash options] in the [Flash control] display and press 2.

C: Adjust flash output and choose the channel and flash control mode.

Choose the flash control mode and flash level for the master flash and the remote flash units in each group.

The following options are available:

Option	Description
TTL	i-TTL flash control.
qA	Auto aperture. Available only with compatible flash units.
M	Choose the flash level manually.

Choose Channel [3].

f: Set the remote flash units to Channel [3].
f: Group the remote flash units.
- Choose a group (A or B).
- There is no limit on the number of remote flash units that may be used. The practical maximum, however, is three per group, as the light emitted by the remote flash units will interfere with performance if more flash units are used.
C/f: Compose the shot and arrange the flash units.
- See the documentation provided with the flash units for more information.
- Test-fire the units and confirm that they are functioning normally. To test fire the units, use the test flash button on the master flash.
C/f: Take the photograph after confirming that the flash-ready lights for all flash units are lit.
