Acquire reference data for the Image Dust Off option in Capture NX-D. Image Dust Off processes NEF (RAW) images to mitigate effects caused by dust adhering in front of the camera image sensor. For more information, refer to Capture NX-D 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.

  • The Capture NX-D Image Dust Off option cannot be used with NEF (RAW) pictures recorded at an image size of [Medium] or [Small].

  • Reference images cannot be viewed using computer imaging software.

  • A grid pattern is displayed when reference images are viewed on the camera.
