Nikon D70S Manuel D’Utilisation

 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.

 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.

To  display the current camera fi rmware  version, 
highlight  Firmware Ver. in the setup menu (

 

155) and press the multi selector to the right. 

 

Press the multi selector to the left to return to the 
setup menu.

When Image Dust Off reference data are viewed on the 
camera, the grid pattern shown at right appears in the 
monitor; histogram and highlights are not displayed. 

 

Files created with Dust ref photo can not be viewed 
using ordinary imaging software.
