HMC Neutral Density
- Available is 3 densities:
- 1-stop (NDx2)
- 2-stop (NDx4)
- 3-stop (NDx8)
- The Hoya glass has 6 layers HMC multi-coatings applied for sharp, glare-free viewing
- Great for shooting waterfalls, moving water and clouds.
- Allows for great control over Shutter and Aperture in bright lighting conditions
In conditions of extreme light intensity, such as sunshine on snowy mountains or on the beach, or when using a cine/video camera, ND (Neutral Density) filters are recommended as essential.
Neutral Density filters are often ignored by photographers, but they have several uses and offer the possibility to achieve otherwise unachievable results. ND filters appear a neutral grey and reduce the amount of light reaching the sensor, they have no affect on color balance. They are available in 1-stop (NDx2), 2-stop (NDx4) and 3-stop (NDx4) light reducing grades in a variety of common sizes.
They have four main uses:
1) To enable slow shutter speeds to be used, especially with fast films, to record movement in subjects such as waterfalls, clouds, cars, seas etc.
2) To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background.
3) To decrease the effective ISO of high speed film (ie: above ISO400) and allow it to be used outdoors in blight situations.
4) 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.
