How to Use ND Filters: An Introduction Read More

This 6.6 x 6.6" Water White Glass IRND Filter from Tiffen Filters provides a 9-stop exposure reduction. Its 2.7 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 features color core technology, which sandwhiches the filter's substrate between two pieces of optical glass. The added infrared protection on this filter helps to eliminate the infrared light that can cause IR pollution on digital cameras without an IR cut filter.
