Use a Neutral Density filter or Infra-Red Pass filter to cover
the lens during focusing to simulate low light conditions on
scene for correct 24-hour focusing. For camera with vari-

fully opened to simulate the worst possible depth of field.
Using a Neutral Density filter or Infra-Red Pass filter will
ensure the iris is fully open for correct setup and adjustment.
Note that statement above is applicable only for Day/Night or
