R132 Rosco Roscolux Supergel - Quarter (1/4) Hamburg Frost

R132 Rosco Roscolux Supergel – Quarter Hamburg Frost is a widely used light diffusion filter that subtly softens the beam edge while preserving beam shape and intensity. It offers minimal diffusion, making it ideal for controlling harsh shadows or blending multiple sources without noticeably altering the quality or direction of the light.

Its popularity stems from its versatility — it’s frequently used on key lights to take the edge off without losing punch, or on practicals and small sources to smooth spill without noticeable diffusion artifacts.
