Ideal for photographing in high contrast situations, the 150 x 150mm Galen Rowell Graduated Neutral Density 0.3 Hard-Edge Filter from Singh-Ray helps to balance exposures and produce imagery with greater highlight and shadow detail. The filter's design places the 0.3, 1-stop density at the top of the filter and then transitions to clear by the center of the filter for a gradual, natural appearance. The hard-edge transition between the density and clear areas is well-suited for photographing scenes with a straight, distinct horizon line as well as when working with a telephoto or long lens. This filter is constructed from optical resin that is both durable and helps to maintain high clarity, and is compatible with the LEE SW150 filter holder.
