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: Flash control i-TTL balanced fill-flash Standard i-TTL fill-flash Description 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. 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. A 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. Using an On-Camera Flash 425
