from a bright, featureless white object, frame the object so that nothing else is visible in

the viewfinder and press the shutter-release button halfway. In autofocus mode, focus

5 Press the shutter-release button the rest of the way down to acquire Image Dust Off refer- ence 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 mes- sage shown at right will be displayed. Choose another reference object and repeat the pro- cess from Step 3.
