The Low-Pass Filter
The image sensor that acts as the camera’s picture element is fitted
with a low-pass filter to prevent moiré. If you suspect that dirt or
dust on the filter is appearing in photographs, you can clean the
filter as described below. Note, however, that the filter is
extremely delicate and easily damaged. Nikon recommends that
the filter be cleaned only by Nikon-authorized service personnel.
