Overview

The Singh-Ray 77mm (Thin Mount) Vari-ND Variable Neutral Density Filter - This neutral density filter gives you the capability to use fast film in bright sunlight. ND filters have several uses and offer the possibility to achieve otherwise unachievable results. They enable the shooter to adjust exposure without affecting color balance. ND filters reduce the amount of light reaching the film.

When used with a digital camera, you can effectively see how this filter works. After the initial exposure, you can check your LCD image and then make whatever change in exposure you feel you need to enhance your image. By rotating the ring, you can either increase or decrease the ND effect. This will be especially useful when trying to achieve "blurred" or "panned" shots.

The filter contains "index" points to help you mark your spot. They do not represent actual ND settings , i.e. non-calibrated - but are there to help you re-set your filter when you wish to recreate the effect.

Note: Singh-Ray cannot predict when vignetting may occur - especially with very wide angle lenses. To avoid vignetting, adjust your focal length, position, and/or composition to remove the vignetting - use your digital camera's display for reference.

Front ring can accept a Mor-Slo 5-stop Solid ND Filter or a Cokin holder for ND Grad Filters 1
Front Min/Max density ring lets you adjust density from 2-2/3 to 8 f/stops

Neutral Density Filters Have Four Main Uses

To enable slow shutter speeds to be used, especially with high speed films, to record movement in subjects such as waterfalls, clouds, or cars
To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background
To decrease the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situation
To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure

Neutral Density Factors

ND.3 (exposure adjustment = 1 stop)
ND.6 (exposure adjustment = 2 stops)
ND.9 (exposure adjustment = 3 stops)
