The Singh-Ray 84 x 120mm 4 Sunset Soft-Edge Graduated Warming Filter helps to specifically add a warm, reddish-orange coloration to skies and other bright areas of an image while allowing a portion of the image to remain neutrally colored. The filter's coloring is densest at the edge and tapers to clear by the middle, with a soft-edged transition between the density and clear areas. The 4 stop color density provides a substantial amount of sunset coloring that is greater than the 3 stop sunset warming filter.

Singh-Ray rectangular filters are constructed from CR-39 optical resin for high image clarity and overall durability. This filter is compatible with the Cokin P filter holder and measures 3.3 x 4.7" / 84 x 120mm.
