K&F Concept Black Mist 1/4 filter 4 × 5.65″ for matte boxes

Matte Box Cinema — Black Mist filter, softens the highlights and takes off digital sharpness. It suits portraits, night streets and video wherever the picture should look softer and less digital without being reworked on the computer afterwards.

• 28 anti-reflective layers, reflectance 0.2 %
• The surface repels water and grease and resists scratches

Softer highlights, a film look

Black Mist scatters the light around bright areas — street lamps take on a gentle glow, blown highlights soften and skin loses its digital hardness. Contrast in the deep shadows drops a little, so the picture looks more filmic straight out of the camera. Unlike an effect added in post, the diffusion follows the actual light in the scene.

Easy to clean outdoors

The surface repels water and grease, so drops run off and fingerprints wipe away without smears; the coating also stands up to cleaning in the field.

The glass carries 28 anti-reflective layers and reflects only 0.2 % of the light, so no ghosting or veiling appears against the light. The 4″ × 5.65″ size is the cinema standard, so the filter fits common matte boxes and filter trays. It is not screwed onto the lens but slid in front of it, which allows several filters to be stacked and swapped without touching the lens.
