NiSi Filter Black Mist 1/8 52mm – Soft diffusion with black specks

The NiSi Black Mist 1/8 (52mm) adds a subtle, film-like character to your images. It gently diffuses light sources while keeping shadows deep and well-defined. At the same time, it lowers contrast and softens skin details, which makes it well suited for portrait work.

How this Black Mist filter affects your images

The filter creates a soft, pastel-like quality of light across the frame. Light sources receive a pleasant diffusion that can reduce harsh highlights without removing the depth in darker areas. Shadows remain shaded and black, preserving mood and shape in your composition.

Because the filter lowers contrast and softens wrinkles and blemishes, it is particularly useful when you want a flattering look for faces. Meanwhile, it provides little loss of details across the image compared to traditional diffusion filters, so overall image information is retained.

Strengths and selection

The NiSi Black Mist series is available in three strengths: 1/2, 1/4, and 1/8. The 1/2 offers the strongest effect, the 1/4 gives a moderate effect, and the 1/8 provides only a small, subtle effect. Choose the strength that matches how much diffusion and softness you want in your shots.

Build and sizes

The filter frame is made of brass, which makes it easy to screw on and off your lens. You can select the filter in a range of common thread sizes to match your lenses.

• Available sizes: 49, 52, 67, 72, 77, 82 and 95mm

Key specifications

Use cases and practical tips

Use the 1/8 if you want only a gentle softening while keeping most of the original image character. Opt for 1/4 for a balanced, cinematic diffusion. Choose 1/2 when you need stronger atmosphere and more visible bloom around highlights. The black speck layer helps maintain shadow depth while still producing diffusion, making this filter suitable for portraiture and atmospheric scenes.
