Flash Color Information Communication
SB-800 fl ash units can provide the camera information on the color tempera-
ture of the fl ash. When white balance for the D2H is set to A (Auto; 51),
this allows automatic white-balance adjustment in response to fi ne variations
in fl ash output. This feature can be used with Advanced Wireless Lighting
and Auto FP High-Speed Sync.
To prevent white balance from being adjusted in response to color tempera-
ture variations, select a white balance setting other than A (Auto). Select
(Flash) for fi xed white balance.
Auto FP High-Speed Sync
Auto FP High-Speed Sync is activated automatically at shutter speeds faster
than ½50 s, allowing auto fl ash control at all shutter speeds up to and includ-
ing

8,000 s (normal sync control is used at shutter speeds slower than ½50 s,
including ). As a result, the fl ash can be used without concern for
maximum sync speed, even in daylight shots taken at maximum aperture.
This feature supports Advanced Wireless Lighting.
To use Auto FP High-Speed Sync, choose 1/250 (FP auto) for Custom Setting
e1 (Flash sync speed).
The SB-800
The Nikon SB-800 is a high performance Speedlight with a guide number of 53/174
(m/ft, 35-mm zoom head position, ISO 200, 20 °C/68 °F). It can be powered by four
AA batteries (fi ve AA batteries when powered by the supplied SD-800 battery pack)
or by SD-6, SD-7, or SD-8A power sources (available separately). For bounce-fl ash or
close-up photography, the fl ash head can be rotated through 90 ° above and 7 ° below
the horizontal, 180 ° left, and 90 ° right. Auto power zoom (24–105 mm) ensures that
the illuminating is adjusted in accord with lens focal length. The built-in wide panel
can be used for illuminating angles of 14 mm and 17 mm. The SB-800 is equipped
with an illuminator to assist in adjusting settings in the dark. Custom settings are avail-
able for fi ne-tuning all aspects of fl ash operation.
