ND64 filter, six-stop light reduction, essential tool for strong light photography, optical component.

The ND64 filter (also known as the ND64 neutral density filter) is a type of neutral density filter that evenly reduces the amount of light entering the lens to 1/64 of the original, equivalent to a 6-stop exposure reduction.

• Main Function: Allows the use of slower shutter speeds (e.g., 1 second) or larger apertures (e.g., F1.4) in bright lighting conditions, enabling creative effects such as silky water flow, motion blur, and shallow depth of field while avoiding overexposure.

• Typical Scenarios: Shooting moving clouds, waterfalls, or waves at noon on sunny days, or eliminating pedestrians and vehicles in urban time-lapse photography.

• Specifications and Features: Multi-coated optical glass, no color cast, anti-glare, supports wide-angle use without vignetting. Some brands feature magnetic or snap-on designs for quick and secure installation.
