Hoya 77mm NDx4 / ND4 HMC Filter

Neutral density filters (also known as NDs) produce a grey neutral tone and are used to reduce light, enabling more control over exposure and depth of field without affecting colour or contrast. They are especially useful in bright light conditions to avoid overexposure. Since ND filters uniformly reduce light at all wavelengths, there is no effect of the colour rendition.
