The Singh-Ray 84 x 84mm Mor-Slo ND 15-Stop Filter is a solid neutral density filter providing an exposure reduction of about 15 stops. This 4.5 optical density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Mor-Slo filters are especially adept at maintaining neutral color fidelity and minimizing color casts that are inherent to such strong densities; however, a slight warming of the image can be expected due to the exaggerated exposure length needed to compensate for the 4.5 density.
Singh-Ray Mor-Slo rectangular filters are constructed from highly-polished proprietary glass to provide notable image quality and clarity. This filter is compatible with the Cokin P filter holder and measures 3.3 x 3.3" / 84 x 84mm.
