Acquire reference data for the Image Dust Off option in NX Studio. Image Dust Off processes NEF (RAW) pictures to mitigate effects caused by dust adhering in front of the camera image sensor. For more information, refer to NX Studio’s online help.

A lens with a focal length of at least 50 mm is recommended when recording Image Dust Off reference data. When using a zoom lens, zoom all the way in.

  1. Select Start.

    Highlight Start and press J. A message will be displayed.

  2. Frame a featureless white object in the display.

    With the lens about ten centimeters (four inches) from a well-lit, featureless white object, frame the object so that it fills the display 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. Acquire dust off reference data.

    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 a message will be displayed. Choose another reference object and repeat the process from Step 1.

Image Dust Off Reference Data

The same reference data can be used for photographs taken with different lenses or at different apertures. Reference images cannot be viewed using computer imaging software. A grid pattern is displayed when reference images are viewed on the camera.
