Walimex pro Black Diffusion 1/4 Filter Nano 49 mm – Creative Control for Photo and Video: The Walimex pro Black Diffusion 1/4 Filter Nano with a diameter of 49 mm is a high-quality diffusion filter that specifically reduces highlights and slightly lowers the overall contrast of a scene. Also known as a Mist Filter or Black Mist Filter, it creates a soft, diffuse effect and gives images a softer, cinematic quality. With its 30-fold nano-coating, this fog filter is particularly scratch-resistant, dirt-repellent, and free from reflections. Thanks to its slim design with a height of only 3.3 mm, it is also ideal for wide-angle lenses without causing vignetting. Special advantages of the nano-coating: This camera filter impresses with its top-notch craftsmanship. The 18-fold nano-coating reliably protects the filter from scratches, minimizes unwanted reflections, and makes cleaning easier, as dust and dirt adhere less. Versatile applications in videography: The Black Diffusion Filter is especially popular for projects that require a cinematic aesthetic. In music videos, short films, or commercials, it provides a soft look with gentle contrasts and highlights. In portrait videography, it flatters skin tones, conceals minor imperfections, and reduces the need for digital retouching. Even in low-light scenes, the lens filter reveals its special effect: light sources such as candles, street lamps, or neon lights acquire an atmospheric "glow" that enhances the mood. Use in photography: This camera filter also opens up versatile creative possibilities in photography. In wedding photography, the fog filter highlights the romantic atmosphere with soft highlights. Landscape photographers use it to subtly soften harsh contrasts during sunrises or sunsets.
