To use this feature, select Image Dust Off Ref Photo, choose either Start or Clean Sensor
and then Start, and then press OK. If directed to do so, the camera will first perform a
self-cleaning operation by applying ultrasonic vibration to the low-pass filter that resides
on top of the sensor. Then, a screen will appear asking you to take a photo of a bright
featureless white object 10 cm from the lens. Nikon recommends using a lens with a
focal length of at least 50mm. Point the D7000 at a solid white card and press the shut-
ter release. An image with the extension NDF will be created, and can be used by Nikon
Capture NX 2 as a reference photo if the “dust off” picture is placed in the same folder
as an image to be processed for dust removal.
Battery Info
This screen is purely informational; there are no settings to be made. When invoked,
you can see the following information:
■ Bat. Meter. The current battery level, shown as a percentage from 100 to 0 percent.
■ Pic. Meter. This shows the number of actuations with the current battery since it
was last recharged. This number can be larger than the number of photos taken,
because other functions, such as white balance presetting, can cause the shutter to
be tripped. This display is not shown when the MB-D11 battery pack is attached
and loaded with AA batteries.
■ Battery age. Eventually, a battery will no longer accept a charge as well as it did
when it is new, and must be replaced. This indicator shows when a battery is con-
sidered new (0); has begun to degrade slightly (1,2,3); or has reached the end of its
charging life and is ready for replacement (4). Batteries charged at temperatures
lower than 41 degrees F may display an impaired charging life temporarily, but
return to their true “health” when recharged above 68 degrees F. This display is not
shown when the MB-D11 battery pack is attached and loaded with AA batteries.

mitter for instructions on configuring the device and your computer’s WiFi network.
This menu entry is grayed out, and available only when the WT-4 is connected.
