D i-TTL Flash Control
When an optional flash unit that supports the Nikon Cr
eative 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:
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.
Standard i-TTL fill-flash is activated automatically when [Spot metering] is selected.
