Dust off Ref Photo
Acquire reference data for the Image Dust Off option in Capture NX
(available separately; A 156). Image Dust Off is used to reduce the
effects of dust in NEF (RAW) photographs. For more information,
see the documentation provided with Capture NX.
Acquiring Image Dust Off Reference Data
1 Highlight Start or Clean sensor, then start and press
Q.
When acquiring image dust off reference data after photographs
have been taken, select Start. The message shown at right will be
displayed.
When taking photographs after acquiring image dust off reference
data, select Clean sensor, then start. The message shown at right
will be displayed after the image sensor is cleaned (A 160).
“ref” will appear in the viewfinder.
Press O to exit without acquiring image dust off reference data.
2 With the lens ten centimeters (four inches) from a well-
lit, featureless white object, frame the object so that it
fills the viewfinder and then press the shutter-release
button halfway.
In autofocus mode, focus will automatically be set to infinity; in
manual focus mode, set focus to infinity manually.
3 Press the shutter-release button the rest of the way
down to acquire image dust off reference data.
The monitor turns off when the shutter-release button is pressed.
If the reference object is too bright or too dark, the camera may be
unable to acquire image dust off reference data and the message
shown at right will be displayed. Choose another reference object and
repeat the process from step 1.
B Notes on Image Sensor Cleaning
If photographs that will be processed with Image Dust Off have already been recorded, DO NOT
clean the image sensor before acquiring image dust off reference data. If the image sensor is
cleaned after photographs are taken, but before image dust reference data are acquired, Image Dust
Off will be unable to locate dust and remove its effects. This camera automatically cleans the image
sensor when the camera is turned on and off (default setting). Selecting Cleaning off for Clean
image sensor>Clean at (A 161) in the setup menu is recommended when acquiring image dust
off reference data.
