The 52mm Tiffen Day for Night Monochrome Glass Filter creates the illusion of twilight when filming in daylight by underexposing about two stops and adding a bluish overcast. This cost-effective solution reduces the need for night shoots and extra lighting expenses. Made with Tiffen's ColorCore technology, the filter material is permanently laminated between two sheets of precision optical glass, ensuring consistent density, accurate color control, and reliable performance. Its unique visual effect makes it a valued tool for filmmakers seeking dramatic, atmospheric results.
