Diffusion Filters

Why use diffusion filters?

Diffusion filters soften the image of today's high-res shots and create a pleasant filmic look, without defocusing the scene. At Schneider-Kreuznach we offer four different types of diffusion filters, each creating its own, unique effect.  

Most of the modern cine lenses produce high-res shots that show everything – every wrinkle, every pore. Diffusion filters smoothen fine details and add a subtle glow to highlights without making sacrifices to the overall sharpness of the image. 

Schneider-Kreuznach offers four types of diffusion filters. Classic Soft® filters create a precisely controlled softness that is overlaid on a sharp, in-focus image. Black Frost® flairs highlights and tones down contrast while retaining rich blacks. Hollywood Black Magic® combines both: It is the specialist for a pleasant filmic look and produces a constant smooth halation while maintaining rich blacks and colors. Radiant Soft® is Schneider-Kreuznach's skin enhancer that tones down imperfections and gives skin a soft glow. For more info, check our Factsheets below. 

All our Diffusion Filters are available in different strengths, given that both the focal length and the F-Stop affect the level of diffusion. Generally speaking, the longer the focal length and the more light on the subject the stronger is the effect of the filters.
