Neutral density filters use the absorption or reflection characteristics of materials to attenuate the intensity of light. After the light in the visible region to the near-infrared region passes through the neutral density filter, different wavelengths are attenuated in the same proportion. This makes the optical element maintain approximately equal light energy transmittance in a wide band.

Product features
Neutral density filters are suitable for cameras that use large apertures or slow shutter speeds during the day to create special effects.
(1), ND-2: can reduce the first-level aperture and 50% of the amount of light;
(2), ND-4: can reduce 2 levels of aperture and 75% of the amount of light;
(3), ND-8: 3 levels of aperture and 87.5% of light can be reduced;
(4), ND-400: It can reduce the light quantity of 9 stops, which is suitable for long-time exposure during the day and shooting the sun.
