The F6 supports flash photography when an optional Speedlight is
mounted on the camera’s accessory shoe. A flash can be used not
only when natural lighting is inadequate, but also to fill in shadows,
illuminate backlit subjects, and even to add a catchlight to the eyes
of a portrait subject.
The Creative Lighting System
When used with an SB-800 or SB-600 Speedlight (available separately), the
F6 supports the full range of options available with the Nikon Creative
Lighting System (CLS), including i-TTL flash control, FV Lock, Auto FP High-
Speed Sync, and AF-assist illumination for multi-area autofocus. When used
with multiple SB-800/SB-600 flash units, the F6 also supports Advanced
Wireless Lighting.
• i-TTL Flash Control
When used with the F6 and set to TTL, the SB-800/SB-600 automatically uses
one of the following types of i-TTL flash control:
i-TTL Balanced Fill-Flash
The Speedlight emits a series of nearly invisible preflashes (monitor preflashes)
immediately before the main flash. Preflashes reflected from objects in all areas of the
frame are picked up by the five-segment TTL flash control sensor or 1,005-pixel RGB
sensor and are analyzed in combination with information from the Matrix Metering
system to adjust flash output for natural balance between the main subject and
ambient background lighting. When a type G or D lens is used, distance information
is included when calculating flash output. Precision of calculation can be increased
for non-CPU lenses by providing lens data (focal length and maximum aperture; x
144). Select a metering system on the F6 other than Spot Metering. (With Spot
Metering, the Flash mode automatically switches to Standard TTL flash.)
Standard TTL Flash
Flash output is adjusted to ensure the main subject is correctly exposed; background
brightness 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 TTL flash is activated automatically when Spot
metering is selected.
Monitor Preflash will not normally operate in Standard TTL flash; it does, however,
operate in Auto FP High-Speed Sync or FV Lock (Standard i-TTL flash).
Flash may not fire when the background is extremely bright.
