This 3-Stop, 77mm Hard-Edge Graduated ND Filter with Rotating Frame from Ice can darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions. The filter provides a 3-stop increase in density, with a hard-edged line of transition between the dense and clear areas. This filter is ideal for landscape photographers, as a hard-edged line is particularly useful for images that feature strong horizons or any hard transition between the sky and land, like seascapes and sunsets.
This graduated ND filter is made of optical glass for image sharpness. The rotating filter ring is made of lightweight, durable aluminum, and features front threads that allow additional filters, a lens hood, or a lens cap to be attached.
