Performing Automatic Dust Erasure Processing

The Dust Delete Data that is appended to images shot with the camera that can attach this data, can be used to automatically erase dust spots. For information on compatible cameras, refer to the "Digital Photo Professional Instruction Manual" (PDF electronic manual).

  1. In the main window, select an image appended with Dust Delete Data.

  2. Click the [Stamp] button.

  3. When the image has redrawn itself, click the [Apply Dust Delete Data] button.

    • Dust spots are erased in a single operation.

  4. Click the [OK] button to return to the main window.


    • The [ ] mark is displayed on an image from which dust spots have been erased.


Dust Delete Data is not attached to images having settings specified during RAW processing on the camera for distortion correction, chromatic aberration correction, etc. As a result, you cannot perform automatic dust erasure processing on such images.


Additional information
  • The dust-erased image can be reverted to its original condition at any time
  • A dust-erased image is displayed or printed as a dust-erased image. However, since the dust on the image is not actually erased, you can always revert to the original image by clicking the [Undo] button in the copy stamp window or performing the "Re-Editing an Image" procedure.
  • Check dust erasure in the copy stamp window
  • Check dust erasure in the copy stamp window. Images before dust erasure are displayed in other windows and you will be unable to check them.
  • Printing dust-erased images
  • You can print as a dust-erased image by printing it in DPP.
  • The [Apply Dust Delete Data] button cannot be clicked
  • Even with an image that has Dust Delete Data attached to it in the camera, if there is no dust to remove by DPP from the image, the [Apply Dust Delete Data] button will be disabled.
  • To erase dust spots that cannot be erased with the automatic dust erasure processing
  • In automatic dust erasure processing, dust spots are erased based on information relating to dust saved in the Dust Delete Data. However, there may be cases where you will not be able to erase dust spots depending on the type of dust. If this occurs, erase those dust spots using the repair function or the copy stamp function.
  • The image becomes a dust-erased image when saved as a separate image
  • The dust-erased JPEG or TIFF image actually becomes a dust-erased image when saved as a separate image. (Saving Editing Content to an Image)

Useful functions of the copy stamp window
  • Checking the dust erased spots

  • Canceling a specified erased dust spot only
  • After step 3, you can press the <Shift> + <F> keys or the <Shift> + <B> keys to display the erased dust spot, and then press the <Shift> + <Del> keys to cancel only the erased dust spot displayed.
  • Switch between full screen display/normal screen display using shortcut keys
  • You can also switch between full screen display/normal screen display by pressing the <Alt> + <Enter> keys.
  • Applying the dust erasure result to another image
  • You can apply dust erasure to the same place in another image by clicking the [Copy] button to copy the dust erasure results and then displaying the other image to which you want to apply the results and clicking the [Paste] button.

Automatic Dust Erasure Processing in the Main Window

In the main window, you can also automatically erase dust spots in multiple images appended with Dust Delete Data.

  1. Select multiple images appended with Dust Delete Data, and then select the [Adjustment] menu → [Apply Dust Delete Data].

    • Dust spots in all the selected images are erased in a single operation.
