SELECTION OF FILTERS
With the aperture and shutter, the camera can control
the amount of light, but not the quality of light.
Therefore, it is necessary to filter the light com-
ponents that are not wanted for visual expressions.
Filters are useful for this purpose.
Filters for color and B&W films
Skylight (1A):
For absorbing ultraviolet rays. It yields
natural colors on the part of a subject in the shade
under a blue sky by filtering the light from the sky.
It can be used to protect the lens, but it is not
recommended to use this filter for subjects which are
not affected by ultraviolet rays or a blue sky because
the color balance may be impaired.
L3 (UV):
In the open air on a bright day, there are a
lot of ultraviolet rays to which photographic films are
sensitive although they are invisible to the human
eye. Affected by these rays scattering in the air,
distant landscapes may turn out whitish and unclear.
The skylight filter cuts off detrimental ultraviolet rays.
It can always be used for lens protection.
ND2/ND4:
Neutral gray filter for reducing the light
quantity without affecting the color and contrast.
Use this filter if you want to open the aperture for a
blurred background, or produce special "blur" effects
with a slow shutter speed, or to reduce the light
intensity without increasing the shutter speed on a
reflex telephoto lens which has no aperture control
mechanism. Available in two types: ND2 for reducing
the light intensity by one stop and ND4 for reducing
it by two stops.
C-POL (circularly polarizing filter):
For blocking
the light reflected from the surface of glass, water
and tile to take sharp pictures of fish in the water,
subjects behind a show window, etc. It can also be
used as a contrast filter for color pictures of land-
scapes, because it cuts off the light reflected from
dust or vapor under a blue sky as well as the surface
of leaves and grass. As this is a circularly polarizing
filter it can be used on cameras using a half-mirror
such as the OM-3Ti.
