The Schneider 6.6x6.6" Double Classic Black Soft 1/4 Water White Glass Filter combines the benefits of Classic Soft with the subtle effects of Black Frost 1/4. It is ideal for close-ups, and can be used to facilitate a seamless transition in the look and continuity from scene to scene.
Black Frost filters flare highlights, mute colors, and tone down contrast, while retaining rich blacks. This is a very useful combination of effects for 16mm and 35mm film, as well as for HD and standard video. These are primarily styling, or mood modifying filters.
