The Tiffen 4 x 5.65" Combination 81EF/ND 0.9 Filter brings together the benefits of two filters in one. With a harmonious blend of an amber light-balancing 81EF and a 0.9 neutral density filter, this filter offers versatile advantages. The ND component reduces exposure by 3 stops, making it ideal for achieving wider apertures or slower shutter speeds. Meanwhile, the 81EF filter imparts a gentle color transformation by cooling the color temperature by 650K. This allows for achieving a balanced 3200K temperature when dealing with a prevailing light source of 3850K.

Employing ColorCore technology, this filter embodies precision craftsmanship. The process involves laminating the filter substrate between dual layers of optical glass and then finely grinding it to a remarkable tolerance of 1/10,000th of an inch. Measuring 4 x 5.65" / 101.6 x 143.5mm, this filter encapsulates versatility in a compact form.

• Combination of both an amber light-balancing 81EF and an ND filter.
• 0.9 ND filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.
• 81EF light-balancing filter decreases color temperature and provides a warming effect.
