Time Noise Reduction system
real-time noise reduction can be accomplished in a single shot.
Real time noise reduction is a processing function that suppresses
the random noise that occurs in long exposures. With the Nikon
D2H, the image processing engine does the processing, so a second
exposure is unnecessary and processing occurs quicker.
with other Nikon D-SLR's, double exposure-type noise reduction
can also be turned on thorugh the menu setup for even greater
spot noise reduction in longer exposures.
With the D2H,
due to extra space between the image screen and the surface
of the low pass filter, dust is less likely to be a concern.
In addition, the design enables dust to be easily wiped off
in the unlikely event it does affix itself.

Capture 4 can also be used to minimize the effect
of any dust. The reference data can be captured by selecting
"Image Dust Off Data Capture" in the setup menu and
shooting a plain white backdrop, such as a sheet of white paper.
The data is saved as a file with the extension ".ndf"
(Nikon Dust image File). When displayed on the camera's LCD
monitor, this data appears with a crosshatched pattern to clearly
identify it as reference data.
Image Dust Off can be used with the D100
as well as with the firmware updated versions of the D1H and
D1X (with greater memory capacity). It cannot be used with the
D1 as well as D1H and D1X cameras that have not had the firmware
updated. The D100 and firmware updated D1H/D1X do not have a
mode for shooting in Image Dust Off. However, following the
steps listed below enables raw (NEF) images to be used as Image
Dust Off data.

the viewfinder, the high-resolution LCD monitor has a resilient
tempered glass surface and offers clear viewing of menus,
playback modes, One-touch Zoom, and the new on-demand information.
A nice feature is that the LCD monitor is now located dead
center, which means the monitor is less likely to get smudged,
partly because the user's nose does not touch the monitor
while looking through the viewfinder.

pushing the playback button, it is possible to view the active

taken. (Confirms active AF point was locked on desired subject
area). This feature is enabled by pushing the multiselector
on the back of the camera.

one button (D2H: playback button), as on the D1X and D1H (monitor
button), initiates the playback mode. When in playback mode,
all functions including playback and delete are possible. Even
during playback, lightly pressing the shutter release button
instantly switches the camera to shooting mode.
playback is enlarged in the same way as on the D100. Press the
"Enter" button and select the enlarge mode with a
single push. Keep the thumbnail button depressed while the "enlarge"
indicator is displayed and rotate the main command dial to incrementally
adjust the zoom. During enlarging, the position of the indicators
can be changed with the multiselector. The zoom feature offers
approximately eight levels of adjustment and magnifies by a
factor of four in terms of length. The magnification ratio will
be smaller if the image size is M.

802.11b Wireless Transmitter WT-1 (optional)
new wireless transmitter attaches to the camera bottom and connects
to the USB port for direct wireless transfer of images to any
IEEE 802.11b compatible access point. There are two types of
antennas. With the standard antenna, data transfer is possible
to approximately 30m (100ft). With the Extended Range Antenna
WA-E1, (pictured below) transfer is possible
for a maximum range of approx. 150 m (500 ft). The distance
may be limited in situations where there are obstacles and such.
It transmits images to an ftp server via a wireless LAN selected
in the camera's menu. There are two possible methods of transmissions.
With the infrastructure mode, the images are sent to an FTP
server via an access point that is on an intranet. With the
ad hoc mode, the images are directly transmitted to an ftp server
on a laptop with a wireless LAN adapter. (Images cannot be sent
to a distant ftp server via an access point on the internet.)
ensure secure wireless data transmission, the D2H offers multiple
levels of security including a choice of three security protocols;
Wired Equivalent Privacy (WEP) encryption, MacAddress, and ESS-ID.
camera and optional WT-1 accessory can be set to various transmission
configurations, including the option to save images on the CompactFlash
card and transmit simultaneously. Four transmission channels
avoid interference and accidental firing. All the configurations
and settings for wireless transmission can be written separately
in a computer text file and applied to multiple cameras by downloading
the file to a CompactFlash card and loading the settings into
WT-1 draws its power supply from the D2H battery, consuming
roughly 20% of its charge during normal usage. Its robust magnesium
chassis construction and water resistant connectors match the
camera's construction and durability.
