Firmware Ver - Nikon D70 Manual

4
Position the lens ten centimeters (four inches) from a bright, featureless
white object. After framing the object so that nothing else is visible in the
viewfi nder, 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.
5
Press the shutter-release button the rest of the way down to acquire Im-
age Dust Off reference data (note that noise reduction turns on automati-
cally when the subject is poorly lit, increasing the amount of time needed
to record the data). The monitor turns off when the shutter-release but-
ton 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.
