Nikon D200 ユーザーズマニュアル

  With the lens ten centimeters (four inches) from a bright, featureless white 

object, frame the object so that nothing else is visible in the viewfi nder and 
press the shutter-release button halfway.  In autofocus mode, focus will 
automatically be set to infi nity; in manual focus mode, set focus to infi nity 
manually before pressing the shutter-release button.  If using the aperture 
ring to set aperture, choose the minimum setting (largest f/-number).

  Press the shutter-release button the rest of the way down to acquire Image 

Dust Off  reference data (note that noise reduction turns on automatically 
when the subject is poorly lit, increasing the amount of time needed to 
record the 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 the message shown at right will 
be displayed.  Choose another reference object and 
repeat the process from Step 1.

The Image Dust Off  feature in Nikon Capture 4 Version 4.4 or later (available separately) 
processes NEF (RAW) photographs to remove the eff ects of dust in the camera imaging 
system by comparing the images to the data acquired with Dust Off  Ref Photo.  It is 
not available with JPEG images.  The same reference data can be used for NEF (RAW) 
photographs taken with diff erent lenses or at diff erent apertures.

Reference images can not be viewed using computer imaging 
software.  A grid pattern is displayed when reference images are 
viewed on the camera.
