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.

Acquiring Image Dust Off Reference Data

  1. Choose a start option.

    • Highlight [Start] and press J to immediately display the [Image Dust Off ref photo] dialog.

    • Highlight [Clean sensor and then start] and press J to clean the image sensor before starting. The [Image Dust Off ref photo] dialog will be displayed when image sensor cleaning is complete.

    • To exit without acquiring Image Dust Off reference data, press G.

  2. 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. 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 and the camera will return to the display shown in Step 1. Choose another reference object and press the shutter-release button again.

Image Sensor Cleaning

Dust off reference data recorded before image sensor cleaning is performed cannot be used with photographs taken after image sensor cleaning is performed. Select [Clean sensor and then start] only if the Image Dust Off reference data will not be used with existing photographs.

Acquiring Image Dust Off Reference Data
  • An FX-format lens with a focal length of at least 50 mm is recommended.

  • When using a zoom lens, zoom all the way in.

  • 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.
