Hoya 67mm HMC NDX4 Filter

A Hoya 67mm HMC NDX4 Filter allows slower shutter speeds to be made use of to document movement in subjects (blur effect) which includes rivers, clouds, cars or even moving individuals.

This filter offers various uses and delivers the chance to obtain otherwise unachievable consequences. ND filters are grey in colour and decrease the degree of light reaching the film. They have no influence on colour balance.

Easily lower depth of field by allowing for wider apertures to be applied, that will help isolate subjects from their background. The lenses are treated with a multi-coating to limit reflections at the filter surfaces which in turn cuts back on flare and ghosting.

Product features:

• Neutral density filters provide wider apertures or longer exposures devoid of impacting colour balance.
• Allows slow shutter speeds to be used, to record motion in subjects such as waterfalls, clouds, vehicles, oceans etc.
• Decreases depth of field by allowing wider apertures to be used, that will help separate subjects from their background.
• Neutral Density Factors are 4x = ND.6 (exposure adjustment = 2 stops, reduces ISO 1/4).
