Except at shallow depths, a speedlight is a must when
shooting underwater because it restores the subject 's
natural colors. A speed light is also convenient as a
main light source at night and in dim light as well as
a supplemental light source to fill in shadows in
daylight.
A number of different speedlights can be used with
the Nikonos-V, including the new dedicated speedlight,
the SB-103 or SB-102, and the SB-101-both of which
can be used both on land and underwater. When
shooting on land, you can also use Speedlights SB-19,
SB-18, SB-16B, SB-15, and SB-E.
To simplify flash photography even further, the
Nikonos-V features fully automatic through-the-Iens
(TTL) flash exposure control. While the shutter is
open, a silicon photodiode (SPO) at the bottom of the
shutter box reads the light as it reflects off the film ;
when the film has received enough light for correct
exposure, the flash unit turns off. TTL flash exposure
control is operable with the SB-103 or SB-102, which
connects directly to the camera, and the SB-18, SB-
16B and SB-15, which connect to the camera through
a sync cord. The Nikonos -V can also be used with a
va riety of Nikon TTL Multiple Flash photographic
accessories. Before shooting, check that the aperture
setting is adequate for the flash-lo-subject distance
and the guide number of the speedl ighl in use.
