Black Diffusion/FX, is a distinctive yet simple diffusion filter, as it is refined in its ability to reduce fine sharp detail and produce a minimal effect on bounced and reduced highlights. The Black Diffusion/FX look, is apparent by its seemingly non-destructive effect, meaning that any reduction in color saturation is kept to a minimum. When used on close ups, facial features, such as eyes and hair remain sharp on the focal plane while finer and unwanted skin detail smoothly blends away.
