Using an On-Camera Flash
D
i-TTL Flash Control
When an optional flash unit that supports the Nikon Creative Lighting
System is attached and set to TTL, the camera uses monitor pre-flashes for
balanced or standard “i-TTL fill-flash” flash control. i-TTL flash control is not
available with flash units that do not support the Nikon Creative Lighting
System. The camera supports the following types of i-TTL flash control:
•
Standard i-TTL fill-flash is activated automatically when [Spot metering] is
selected.

The Sync Terminal
A sync cable can be connected to the sync
terminal (which features a JIS-B locking nut) as
required. Do not connect another flash unit via a
sync cable when performing rear-curtain sync
flash photography with a flash unit mounted on
the camera accessory shoe.
Flash control Description
i-TTL balanced
fill-flash
The camera uses “i-TTL balanced fill-flash” flash control
for a natural balance between the main subject and
ambient background lighting. After the shutter-release
button is pressed and immediately before the main flash,
the flash unit emits a series of monitor pre-flashes which
the camera uses to optimize flash output for a balance
between the main subject and ambient background
lighting.
Standard i-TTL
fill-flash
Flash output is adjusted to bring lighting in the frame to
a standard level; the brightness of the background is not
taken into account. Recommended for shots in which the
main subject is emphasized at the expense of
background details, or when exposure compensation is
used.
