How to Use ND Filters: An Introduction Read More

This 138mm Unmounted ND Filter from Tiffen provides 1-stop of exposure reduction. Its 0.3 optical density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image. By slowing your exposure time or increasing your aperture, you can control depth of field and convey movement more easily. It is designed to fit in the 138mm slot of your matte box.
