Canon EOS-1D Mark IV - Manual (Page 185)

lilNkMlj Appending Dust Delete Data
Normally, the Self Cleaning Sensor Unit will eliminate most of the dust
that might be visible on captured images. However, in case visible dust
still remains, you can append the Dust Delete Data to the image to later
erase the dust spots. The Dust Delete Data is used by Digital Photo
Professional (provided software) to erase the dust spots automatically.
Preparation
• Get a solid-white object (paper, etc.).
• Set the lens focal length to 50mm or longer.
• Set the lens focus mode switch to
<MF > and set the focus to infinity
(oo). If the lens has no distance scale, look at the front of the lens and
turn the focusing ring clockwise all the way.
