Programmed auto (P) When using a
Speedlight with a compatible camera set to
Programmed auto the shutter speed is auto-
matically set to the camera’s sync shutter
speed when using flash. On the camera, the
shutter speed and aperture are automati-
cally made when the subject is focused.
ready light Located on the rear panel of
the Speedlight, the ready light indicates that
the flash is ready to fire.
rear-curtain sync Setting the Nikon cam-
era to rear curtain sync causes the flash to
fire right before the shutter closes.
red-eye reduction A flash mode controlled
by a camera setting that is used to prevent
the subject’s eyes from appearing red in
color. The Speedlight fires multiple flashes
just before the shutter is opened. As a gen-
eral rule, the further the flash head is
located from the camera lens, the less
chance of getting the red-eye effect. You can
combine red-eye reduction with slow-sync
in low light situations.
remote A Speedlight used in a multiple
flash configuration that is not attached to
the camera. The Speedlight attached to the
camera is called a master, where all the
other Speedlights are referred to as
remotes, or slaves. See also master.
reset Pressing the Mode and On/Off but-
tons simultaneously for about 2 seconds on
the Speedlight resets the Speedlight settings
to their default values.
Shutter Priority In this camera mode, you
set the desired shutter speed, and the cam-
era automatically sets the aperture setting
for you. Best used when shooting action
shots to freeze motion of the subject using
fast shutter speeds.
slave See remote.
sound monitor Remote Speedlights auto-
matically emit a beep after they have been
remotely fired and are recharged and ready
to fire again. This sound can be turned off.
The Speedlight also emits a series of beeps
if the flash output isn’t sufficient to illumi-
nate the subject.
standby function The Speedlights ability to
automatically switch to a sleep mode if the
Speedlight is not used for a pre-determined
period of time. The standby function pre-
vents a rapid degradation of the Speedlights
batteries. You can return the Speedlight to
normal ready mode by pressing the shutter
button half-way on the camera.
TTL mode Stands for through-the-lens. This
metering mode allows for automatic flash
output calculated by the camera’s ability
to communicate flash output levels to
the Speedlight per the cameras metered
reading.
underexposure value The amount of
underexposure set on the Speedlight (using
exposure compensation) and indicated on
the Speedlight’s LCD panel.
wireless remote flash unit See remote.
zoom head Also referred to as the
Speedlight’s flash head that has the capabil-
ity of automatically moving the flash tube
forward or backward during automatic flash
operations to match the focal length of the
lens being used.
