The Image Dust Off option in NX Studio does not have desired effect

Image Dust Off may not be available.

As image sensor cleaning changes the position of dust on the sensor, the Image Dust Off feature may not have the desired effect if:

• Image Dust Off reference data recorded after image sensor cleaning is performed are used with photographs taken before cleaning the sensor, or
• Image Dust Off reference data recorded before image sensor cleaning is performed are used with photographs taken after cleaning the sensor.
