HOYA ND8 HMC 58mm
Neutral density filter that reduces the light to an equivalent of 3 f-stops.
HMC (Hoya Multi Coated)
These popular filters are renowned for their ability to minimise reflection at the filter surfaces which reduces flare and ghosting. HOYA HMC filters are recommended for enhancing the performance of today's multicoated lenses.
Neutral density filters are designed to reduce the amount of light entering your camera lens and should not have any other effect on the image. Reducing the amount of light allows for the use of wider apertures or slower shutter speeds for creative and dramatic effect in bright lighting conditions.
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 bright 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.
