| A Uva filter is available as an accessory
for every LEICA M lens. In addition, there is also an
orange and a yellow green filter available for some of
them.
Film, as well as video, often exhibits a greater sensitivity
to what is to us invisible, ultraviolet light. This
is most often outdoors, especially at high altitudes,
where the UV-absorbing atmosphere is thinner; and over
long distances, such as marine scenes. It can show up
as a bluish color cast with color film, or it can cause
a low-contrast haze that diminishes details, especially
when viewing far-away objects, in either color or black-and-white.
Ultraviolet filters absorb UV light generally without
affecting light in the visible region. |
