## Long description

K&F Black Diffusion 1/8 for 4x5.65 Matte Box is a diffusion filter engineered for cinematic video and professional still workflows. The filter reduces contrast and softens specular highlights while maintaining overall image detail and color fidelity. Designed in the 4x5.65 size, it is compatible with popular matte boxes from Tilta and SmallRig and is intended for use where gentle halation and smoother skin tones are required without heavy loss of sharpness.
Advantages
This diffusion filter provides subtle softening of highlights and a controlled bloom around bright points, producing a cinematic look without introducing strong blur or obvious softness. It reduces contrast in high-contrast scenes and helps maintain texture and fine detail. The product is built to fit standard 4x5.65 matte box holders and works with matte boxes from manufacturers such as Tilta and SmallRig, enabling straightforward integration into existing rigs. The optical design aims to preserve color balance and minimize unwanted artifacts.

How to use
Insert the 4x5.65 diffusion filter into an available slot of a compatible matte box, ensuring it sits flat and secure. Position the filter in front of the lens as part of the matte box stack; it can be used alone or combined with other filters such as ND or polarizers, taking care to avoid vignetting on wide lenses. Evaluate the effect at working aperture and exposure settings, and adjust placement in the filter tray to achieve the desired level of halation and highlight rolloff while preserving necessary image detail.
Usage recommendations
Use this diffusion filter when you need subtle highlight bloom and smoother skin rendering without heavy softening. For controlled results, test the filter at the aperture and lighting conditions you plan to shoot in, and pair it with neutral density filters if exposure control is required. Verify matte box fitment before shooting to avoid light leaks or tray movement.
