low ambient light).
(2) Measuring distance may vary depending on targets and
measuring conditions.
(3) Kodak Gray Card, Catalog number E1527795
(4) Normal conditions (normal visibility, object in the shadow,
moderate ambient light).
(5) Difficult conditions (haze, object in direct sunlight,
high ambient light).
