Image Dust Off Reference Data
Image Dust Off reference data are recorded to the
memory card at an image quality of JPEG Fine and an
image size of Large. When the resulting image is played
back on the camera, a grid pattern is displayed and
voice memos can not be recorded. Files created with
Dust Off ref photo can not be viewed using computer
imaging software.

With the lens ten centimeters (four inches)
from a bright, featureless white object, frame
the object so that nothing else is visible in
the viewfi nder and press the shutter-release
button halfway. In autofocus mode, focus
will automatically be set to infi nity; in manual
focus mode, set focus to infi nity manually before pressing the shutter-
release button. If using the aperture ring to set aperture, choose the
minimum setting (largest f/-number).

Press the shutter-release button the rest of the
way down to acquire Image Dust Off refer-
ence data (note that noise reduction turns
on automatically when the subject is poorly
lit, increasing the amount of time needed to
record the data). The monitor turns off when
the shutter-release button is pressed.
If the reference object is too bright or too
dark, the camera may be unable to acquire
Image Dust Off reference data and the mes-
sage shown at right will be displayed. Choose
another reference object and repeat the pro-
cess from Step 3.
