 Appending Dust Delete DataN

408

 

At a distance of 20 cm - 30 cm (0.7 ft. 
- 1.0 ft.), fill the viewfinder with a 
patternless, solid-white object and 
take a picture.

X

The picture will be taken in aperture-
priority AE mode at an aperture of f/22.

 

Since the image will not be saved, the 
data can still be obtained even if there 
is no card in the camera.

X

When the picture is taken, the camera 
will start collecting the Dust Delete 
Data. When the Dust Delete Data is 
obtained, a message will appear.

 

If the data is not obtained successfully, 
an error message will appear. Follow 
the “Preparation” procedure on the 
preceding page, then select [OK]. Take 
the picture again.

After the Dust Delete Data is obtained, it is appended to all the JPEG 
and RAW images captured thereafter. Before an important shoot, it is 
recommended that you update the Dust Delete Data by obtaining it 
again.
For details about using Digital Photo Professional (EOS software, 
p.536) to erase dust spots, refer to the Digital Photo Professional 
Instruction Manual (p.539).
The Dust Delete Data appended to the image is so small that it hardly 
affects the image file size.

Be sure to use a solid-white object such as a new sheet of white paper. If the 
object has any pattern or design, it may be recognized as dust data and 
affect the accuracy of the dust deletion with the EOS software.
