The Tiffen 4×5.65″ IRND Glimmer Glass Filters (Full Set) combines infrared neutral density filtration with Glimmer Glass diffusion to control exposure while adding a distinctive soft-focus characteristic. The filters reduce perceived sharpness, gently diffuse highlights, and enhance skin tones with a polished cinematic texture. The set provides multiple strengths for adapting the diffusion effect while maintaining infrared correction for digital cinema cameras.
