Frame a featureless white object in the viewfinder.
With the lens about ten centimeters (four inches) from a well-
lit, featureless white object, frame the object so that it fills the 
viewfinder and then press the shutter-release button halfway.
In autofocus mode, focus will automatically be set to infinity; 
in manual focus mode, set focus to infinity manually.

Acquire dust off reference data.
Press the shutter-release button the rest of the way down to 
acquire Image Dust Off reference 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.
