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.
Special image moods can only be captured appropriately by the use of neutral density filters - the contrast between the soft water of the brook and the razor-sharp rock formation of the bank or the central perspective of the course of the clouds above weathered industrial monuments. The Rollei Premium Round ND1000 filter extends the exposure time of your camera by ten aperture stops. With this ND filter for 77mm lense size particularly spectacular long-time shots are successful for you.
Gorilla glass®* for the rigours of professional everyday life
Professional photographers and discerning amateurs often look for unusual locations that then offer them rather suboptimal shooting conditions. Therefore equipment must be extremely resistant and high-quality in order to still deliver perfect results after knocks, contact with pointed or sharp objects or inappropriate storage. The Rollei Premium Round ND1000 Filter is manufactured from amazingly resistant Gorilla®* glass produced by the American traditional manufacturer, Corning Inc. In the US Federal State of New York the glass blanks must endure a bath in a boiling alkaline liquid so that an exchange of ions occurs on the molecular level. In this way the glass in the filters gains an enormous increase in surface tension and survives the challenges of merciless professional everyday life without a problem.
A protective layer against dirt and damage and for the best optical characteristics
The additional Luminance Coating that is applied makes theglass surface, which is already very resistant, still more insensitive to persistent oil or water films as well as to heavy soiling and functions as a barrier against mechanical impairments. Distortions and reflections are effectively prevented and the highest degree of colour fidelity of the Rollei filters is guaranteed. You can be sure that you can save the unaltered, accurately coloured graphic data to the memory card and use it later. Already in the development of the Rollei PremiumND1000 Round Filter, strict, irrevocable quality specifications were decreed and constant tests in accordance with the AQL standard guarantee safe elimination of even the slightest defect, which can pass the customary tests in the sector without difficulty. Rollei premium round ND1000 filters are supplied with a sturdy aluminium filter ring in nine sizes from 49 to 82 mm.
