ND filter is the abbreviation for neutral density
filter. The ND filter is used to achieve a uniformly
moderate darkening of the image. In addition, it gives
the image a uniformly neutral grey colour so that the
colour rendition cannot be altered.
An ND filter makes the subject darker by several guide
values thus preventing over-exposed images.
Frequent applications for ND filters include taking
shots with blur effects or of running water under
ND filters are used with various degrees of darkening,
depending on the prevailing light conditions for the
desired aperture and exposure time.
In combination with the integrated polarizing filter
– also known as polarizing filter or CPL – the
additional effects can be achieved: Polarizing filters
produce particularly intense colours in blue skies and
in the plant world.
Polarizing filters suppress unwanted reflections on
non-metallic surfaces and enable the viewer of the
picture to see through reflective glass and reflective
Polarisation and ND filters are gladly used together by landscape, architectural and city photographers in order to exploit and combine the advantages of both categories in the best possible way. The new Rollei Extremium Dark CPL ND filters relieve you of the obligation of constantly connecting and disconnecting ND and polarising screw-in filters.
ND1000 – 10 aperture stops darker for fascinating long exposures
There is already enormous darkening potential contained in the Rollei Extremium Dark CPL ND1000 Filter. The ND1000 filter glass only allows 0.1 percent of the light through, can guarantee mystical blurring effects even in broad daylight and transforms very stormy water surfaces into completely smooth, uniform planes. In architectural photography, only completely static image components remain and you can accurately detect the precise trajectories of the stars in the cloudless night sky.
Adjustment of polarisation on the professional level
Rotate the CPL titanium filter ring and you have an angle range of exactly 90 degrees available in order to continuously vary mirror images and reflections on water or glass surfaces or to intensify the saturation of blue and green components in the sky and in nature entirely as you wish. The overall contrast in the picture is also pleasantly intensified. The range of effects of a professional polarising filter cannot yet be satisfactorily simulated by digital means completely as some parts of the image only become visible for the first time.
Gorilla Glass®*, Luminance Coating, Titanium Ring, Engineered & Quality Controlled in Germany
The 2-in-1 functionality of the new Rollei Extremium Dark CPL ND1000 Filter is unrestrictedly available to you even under the most adverse environmental conditions owing to a 4-in-1 quality initiative by Rollei. All optical elements of the professional circular filter are made from the best Gorilla®* glass of the traditional American enterprise, Corning Inc. An ingenious finishing process on a molecular level provides for its legendary ruggedness with high light transmission values and complete freedom from distortion. The Rollei Luminance Coating provides for extreme colour fidelity and the most minor reflections and increases the scratch resistance of the quality glasses even further. The solid titanium ring reactsutterly imperviously to variations in temperature of an arbitrary intensity and thus protects the high-quality glasses against dreaded material stresses. The Engineered & Quality Controlled in Germany quality management programme was developed specifically by Rollei in order to keep all manufacturing parameters at the highest level and to eliminate even minimal tolerance deviations immediately. You benefit from a quality standard that is unmatched in the industry.
Of course, you can select your Rollei Extremium Dark CPL ND Filter to suit the desired lens diameter. The following sizes are available: 49, 52, 55, 58, 62, 67, 72, 77 and 82 mm.
