The Low-Pass Filter The image sensor that acts as the camera's picture element is fitted with a low-pass filter to prevent moiré. If you suspect that dirt or dust on the filter is appearing in photographs, you can clean the filter using the Clean image sensor option in the setup menu. The filter can be cleaned at any time using the Clean now option, or cleaning can be performed automatically when the camera is turned on or off. ❚❚ "Clean Now" 1 Place the camera base down. Image sensor cleaning is most effective when the camera is placed base down as shown at right. 2 Display the Clean image sensor menu. Highlight Clean image sensor in the setup menu and press 2. D Image Dust Off The Image Dust Off option in Capture NX 2 can not use dust off reference data recorded before image sensor cleaning is performed to retouch photographs taken after image sensor cleaning is performed. If you intend to use Image Dust Off with photographs recorded after image sensor cleaning is performed, we recommend that you record dust off n reference data after cleaning the image sensor. A Image Sensor Cleaning If the options described in this section are not sufficient to remove dust or other foreign objects from the image sensor, clean the sensor manually as described on page 395. 392
