Filter DOUBLE CLASSIC BLACK SOFT - 4x5,65 1/4

The Schneider 4 x 5.65" Double Classic Black Soft  Filter is a step heavier than Schneider's Black Frost effect. By using this filter, you eliminate the need for stacking filters together to achieve the desired degree of diffusion. For close-ups, it is terrific and aids in creating a seamless transition in the look and continuity from scene to scene.
