Tiffen 4x5.65" Night Fog Diffusion Filter

The Tiffen 4x5.65" Night Fog 1/4 Diffusion Filter creates a natural fog effect that softens highlights and produces a wide flare for atmospheric image quality. It reduces contrast without compromising shadow integrity, delivering a balanced and harmonious composition. Professional cinematographers use it to achieve ethereal looks or dramatic day-for-night transformations.

Practical limits of optical diffusion

The 1/4 density provides subtle diffusion that preserves essential image details while softening harshness for a dreamy effect. Stronger grades flatten contrast and desaturate colours more aggressively, which may not suit every creative intent. The filter's contrast reduction technology targets highlights specifically, leaving shadow detail intact.

Capacity for creative control and durability

High-quality materials ensure optimal light transmission and minimal colour distortion for true-to-life fidelity. Robust construction delivers exceptional scratch resistance, protecting the filter during rigorous production use. The 5.65 inch format fits compatible matte boxes, giving cinematographers reliable headroom for consistent atmospheric effects across scenes.
