3 Appending Dust Delete DataN Normally, the Self Cleaning Sensor Unit will eliminate most of the dust that may be visible on captured images. However, in case visible dust still remains, you can append the Dust Delete Data to the image for erasing the dust spots later. The Dust Delete Data is used by Digital Photo Professional (EOS software, p.536) to erase the dust spots automatically. Preparation Prepare a solid white object such as a sheet of paper. Set the lens focal length to 50 mm or longer. Set the lens's focus mode switch to and set the focus to infinity (∞). If the lens has no distance scale, rotate the camera to face towards you and turn the focusing ring clockwise all the way. Obtaining the Dust Delete Data 1 Select [Dust Delete Data]. Under the [z3] tab, select [Dust Delete Data], then press . 2 Select [OK]. X After the automatic self-cleaning of the sensor is performed, a message will appear. Although there will be a shutter sound during the cleaning, no picture is taken. 407
