Appending Dust Delete Data

Dust Delete Data used to erase dust spots can be appended to images. The Dust Delete Data is used by Digital Photo Professional (EOS software) to erase the dust spots automatically.


  • Use an RF or EF lens.
  • Prepare a solid white object such as a sheet of paper.
  • Set the lens focal length to 50 mm or longer.
  • Set the focus mode to MF (), then set the focus to infinity (∞) by turning the focusing ring clockwise, as viewed from the front of the camera.

Dust Delete Data Acquisition

  1. Select [Shooting: Dust Delete Data].

  2. Select [OK].

  3. Shoot a plain white object.

    • Shoot with a plain white object (such as a new sheet of white paper) filling the screen, at a distance of 20–30 cm (0.7–1.0 ft.).
    • Since the image will not be saved, the data can still be obtained even if there is no card in the camera.
    • When the picture is taken, the camera will start collecting the Dust Delete Data. When the Dust Delete Data is obtained, a message will appear.
    • If the data is not obtained successfully, an error message will appear. Check the information in Preparation, select [OK], and shoot again.

Dust Delete Data Appending

Once acquired, Dust Delete Data is appended to still photos captured after that point. Acquiring Dust Delete Data before shooting is recommended.

For details about using Digital Photo Professional (EOS software) to erase dust spots automatically, refer to the Digital Photo Professional Instruction Manual.

File size is essentially unaffected by Dust Delete Data appended to images.


  • If the object has any pattern or design, it may be recognized as dust data and affect the accuracy of the dust deletion with the Digital Photo Professional (EOS software).
  • Dust Delete Data is not added to shots taken under the following conditions.

    • In [Handheld Night Scene] or [HDR Backlight Control] (Special scene mode) shooting
    • In [Fish-eye effect] (Creative filters mode) shooting
    • When multi-shot noise reduction is set
    • When [Distortion correction] in [Shooting: Lens aberration correction] is set to [Enable]
