~ Notes on Image Sensor Cleaning
If photographs that will be processed with Image Dust Off have already been recorded, DO NOT
clean the image sensor before acquiring image dust off reference data. If the image sensor is
cleaned after photographs are taken, but before image dust reference data are acquired, Image Dust
Off will be unable to locate dust and remove its effects. This camera automatically cleans the image
sensor
when the camera is turned on and off (default setting). Selecting Cleaning off for Clean
image sensor>Clean at (~ 161) in the setup menu is recommended when acquiring image dust
off reference data.
