 Hoya Neutral Density FiltersNeutral Density filters are often ignored by photographers, but they have several uses and offer the possibility to achieve otherwise unachievable results. ND filters appear grey and reduce the amount of light reaching the film, they have no affect on color balance. They have four main uses: - To enable slow shutter speeds to be used, especially with fast films, to record movement in subjects such as waterfalls, clouds, cars, seas etc.
- 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 (ie: above ISO400) and allow it to be used outdoors in blight situations.
- To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which would normally cause over-exposure.
Available types of Neutral Density Filter are: x2 - reduces light by 1 stop. x4 - reduces light by 2 stops.x8 - reduces light by 3 stops.x400 - reduces light by 9 stops.Half x4 - Half NDx4,half clear.Center NDx2 - graduated Neutral Density.
HMC - (Hoya Multi Coating) versions have 3 layers of anti-reflective coating on each surface which reduce reflections down to 1-2%. ULTRA -The ULTRA series is a very thin lens particularly useful for modern wide angle lenses. Click the appropriate image below to see available sizes and pricing |
