The Kenko 82mm MC ND400 Filter uses quality materials for the glass and ﬁlter frame so that reﬂection on the lens isn’t interfered with. The glass filter reduces the amount of light reaching the film/sensor and it appears as grey. It offers the possibility to achieve otherwise unachievable results when shooting a bright sun. This has no effect on color balance and the multi-coated glass minimizes the reflection at the filter surfaces that reduces flare and ghosting.
- The ND400 should be used if you need to substantially reduce the amount of light, such as when taking a photograph of the sun.
- It is also used to create different effects from what we actually see.
- Decreasing depth of field by allowing wider apertures to be used, this helps separate subjects from their background.
This filter reduces light values by 8 2/3 stops to just 1/400th of its original intensity and allows safe photography. Photographing solar eclipses and ultra-bright light sources can be extremely dangerous. It can also be used to achieve super slow shutter speeds in daylight to render moving subjects invisible. Enabling slow shutter speeds to be used, especially with high speed films, to record movement in subjects such as waterfalls, clouds, or cars. Decreasing depth of field by allowing wider apertures to be used, this helps separate subjects from their background. Decreasing the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situations. Allowing cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure.
