229Optional Flash Units
A Optical AWL
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 (qA mode), as this may
interfere with exposure. To prevent low-intensity 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.
