Position the sensor windows on the remote flash units to pick up the light from the
master flash (particular care is required if the camera is not mounted on a tripod). Be
sure that direct light or strong reflections from the remote flash units do not enter the
camera lens (in TTL mode) or the photocells on the remote flash units (AA mode), as
this may interfere with exposure even when – – is selected for Optional flash. To
prevent timing flashes emitted by the master flash from appearing in photographs
taken at short range, choose low ISO sensitivities or small apertures (high f-numbers).
After positioning the remote flash units, take a test shot and view the results in the
camera monitor.

❚❚ Commander Mode
Although there is no limit on the number of remote flash units that may be used, the
practical maximum is three. With more than this number, the light emitted by the
remote flash units will interfere with performance.
Use a camera-mounted SB-500 as a master flash controlling one or more
remote optional flash units in up to two groups (A and B) via Advanced Wire-
less Lighting.
