Black Diffusion FX

The Black Diffusion FX filter is designed to soften fine sharp details with little effect on bounced and reduced highlights. BDFX has a minimal impact on colour saturation, maintaining a seemingly non-destructive look. When used for close-up shots, the filter smoothly blends away unwanted skin detail while keeping facial features such as eyes and hair sharp on the focal plane.

To prevent overly blurring specular highlights, which could result in stronger halation, the Black Diffusion FX filter has an embedded optical softening element. This element plays a crucial role in controlling the amount of optical softening that occurs.
