Rodenstock Neutral Density

Rodenstock Neutral Density filters, reduce all visible colors equally, e.g. by two f-stops. This allows motion blur to be achieved with a longer exposure time than would otherwise be permitted by the brightness of the illumination and the film speed or sensor sensitivity. They also provides less depth of field with a larger aperture . Another application is the light reduction in situations where the brightness is too high for a correct exposure with the shortest exposure time available at the given film speed or sensor sensitivity. As the effect of ND filters cannot be replaced by digital imaging software at a later date, these filters offer many advantages for digital photography. Keep up to date with our Rodenstock filters news on our knowledgebank.

Neutral density (ND) filters

These neutral density (= gray tinted) glass filters, also known as ND filters, reduce all visible colors equally, e.g. by two f-stops. This allows motion blur to be achieved with a longer exposure time than would otherwise be permitted by the brightness of the illumination and the film speed or sensor sensitivity. Examples are images of running water or smear effects with panning camera for car, motor bike or horse races. Alternatively such a filter provides less depth of field with a larger aperture, e.g. for focusing portraits in front of a blurred background, even with lenses with a shorter focal lengths than that of telephoto lenses. Another application is the light reduction in situations where the brightness of the motif is too high for a correct exposure with the shortest exposure time available at the given film speed or sensor sensitivity. For instance images of snow or desserts in bright sunlight. As the effect of ND filters cannot be replaced by digital imaging software at a later date, these filters offer many advantages also for digital photography.

Rodenstock ND Filters are available in different densities for an extension of exposure time by a factor of 2, 4 or 8 or for a wider aperture by 1, 2 or 3 f-stops alternatively.

WARNING: These ND filters must not be used as solar filters for observing the sun! For this purpose special solar filters are necessary with a much stronger absorption power not only within the visual range but also in the even more dangerous infrared range (which can burn the retina!) available in astro shops.

The Rodenstock ND Filters are available with a slimline mount in sizes from 49 mm to 95 mm and 105 mm and with a standard mount in the sizes 100 mm, 112 mm and 127 mm. All of these filters are fitted with a female thread at the front side and a male thread of the same size at the rear. So an additional filter or a lens hood can be fixed.

Image examples:

Without filter: The motif brightness makes a shutter speed of 1 / 60 s necessary despite an f-stop of 16. Water appears frozen.

With an ND filter 8x at aperture 16 and the same brightness and film speed, the time is 1 / 8 s for “flowing” water.
