With the lens about ten centimeters (four inches) from a well-lit, featureless white object, frame the object so that it fills the display and then press the shutter-release button halfway.

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

If the reference object is too bright or too dark, the camera may be unable to acquire Image Dust Off reference data, in which case a message will appear and the camera will return to the display shown in Step 1. Choose another reference object and press the shutter-release button again.
Caution: Image Sensor Cleaning
Dust off reference data recorded before image sensor cleaning is performed cannot be used with photographs taken after image sensor cleaning is performed. Select [Clean sensor and then start] only if the Image Dust Off reference data will not be used with existing photographs.
