NiSi Filter Black Mist 1/4 77mm – soft, pastel-like diffusion with black speck layer for flattering portraits

This NiSi Black Mist 1/4 filter adds an extra dimension and character to your images by softening highlights and reducing contrast without eliminating deep blacks. It diffuses light sources to create a pleasant glow while preserving shadow density. At the same time, the filter helps soften wrinkles and blemishes, making it well suited for portrait work.

How the Black Mist 1/4 affects your images

The Black Mist 1/4 provides a medium level of diffusion. It reduces contrast and tempers excess sharpness, yet retains shadow richness so blacks remain deep. Additionally, light sources gain a gentle diffusion that enhances atmosphere without overpowering detail. As a result, faces benefit from a subtle smoothing effect that reduces the appearance of blemishes and fine lines, which is especially useful for portrait photography and filmmaking.
