Wireless Transmitter WT-4/4A

Photographers and editors working in large, crowded venues know well the logistical nightmare of load-
ing, editing and backing up images on assignment. Now with the new WT-4/4A, which supports IEEE
802.11a as well as IEEE 802.11b/g, the reach of wireless image transmission has made radical strides
toward speed, simplicity and efficiency. To quicken the workflow, the supplied Thumbnail Selector lets
you automatically transmit thumbnails from the transmitter’s buffer memory to a remote personal com-
puter first, where an editor can select the desired images before the complete data is sent. That way,
only the full data from desired images has to go through, saving precious assignment hours. This is
especially useful for teams of photographers, as up to five cameras can be connected at one time.
Supporting wide-ranging network and security protocols, the WT-4/4A is compatible with a variety of
system environments. Image transfer using wired LAN

is also available via Ethernet.
Supplied case
The supplied holder case can be
attached to a belt or hung from the
neck or shoulder with a neck strap.
WT-4/4A connected with the D3
WT-4/4A can also be used with the Nikon D300.
With the D3’s new Scene Recognition
System, most sophisticated digital SLR light-
ing systems become even more intelligent.
Now when you use Nikon’s Creative Lighting
System – no matter which compatible Nikon
Speedlights you use — the SB-800, SB-600
or SB-400 — you will appreciate the i-TTL
improvements, especially when using a
single Speedlight. That’s because instead
of using the conventional 5-segment Multi
Sensor to evaluate monitor pre-flashes in
i-TTL Balanced Fill-Flash, the D3 utilizes the
1,005-pixel RGB sensor for a more refined
flash metering evaluation. With this system,
overexposure is reduced to a degree never
before achieved, even with small subjects,
which tend to be overexposed. Metering
accuracy for a scene containing highly
reflective objects has also been improved.
These improvements are made possible with
the highlight analysis function of the Scene
Recognition System, which correctly calcu-
lates the brightness range to be reproduced
and determines background exposure. This
level of single-Speedlight sophistication
can be indispensable for photojournalists
or other professionals who rarely have a
second chance to make the shot. In addition,
the Creative Lighting system is compatible
with Advanced Wireless Lighting’s use of
multiple Speedlights, for comprehensive
control over scene lighting.
