Photograph a solid-white object.
Keep a distance of 20 - 30 cm / 0.7 -
1.0 feet and fill the viewfinder
completely with the white object.
Then take the picture.
X The picture will be taken in the
aperture-priority mode with an
aperture of f/22.
Since the captured image will not be
saved, installing a CF card in the
camera is not necessary. The image
data will still be obtained.
X After the image is captured, the data
is obtained. When it is completed, the
“Data obtained” screen will appear.
Select [OK] and press <0>. The
menu will reappear.
After the Dust Delete Data is obtained, it is appended to all the JPEG or
RAW images captured thereafter. The data will also be appended to
images taken in the Basic Zone modes. Before an important shoot, you
should update the Dust Delete Data by obtaining it again.
Regarding the automatic dust erasure with the bundled software, see
the Software Instruction Manual in the CD-ROM.
The Dust Delete Data appended to the image is so small that it hardly
affects the image file size.
