The Tiffen 67mm Black Satin 1 Filter helps to reduce the overall contrast of an image and better control the highlights within a scene. In addition to rendering highlights with a grittier, more grainy appearance, this filter also helps to subtly soften facial blemishes and wrinkles for a natural, refined look. The 1 density provides less contrast and highlight reduction than the 2, while still producing a soft, yet natural appearance.
