Neutral Density Filters
- Spectrally Flat
- Maximum Accuracy and Neutrality at Moderate Price
- Use Stacks to Create Intermediate Density Values
Neutral Density (ND) Filters are optical filters that reduce the intensity of light entering a camera or optical system without affecting its color balance. They are commonly used in photography, videography, and scientific applications to control exposure and achieve longer shutter speeds or wider apertures. ND filters are essential for capturing high-quality images in bright lighting conditions. Available in various densities, they provide flexibility for different light conditions and creative effects.
