The 82mm Tiffen Day-for-Night Lavender-Blue Cooling Filter produces a day-for-night photographic effect. It is an effect that makes a scene recorded in daylight to appear as if it were at twilight. Day for night filters are a cost-effective alternative to night shooting where overtime charges may apply to cast, crew and rental equipment of lighting gear.
Tiffen's ColorCore glass is produced through a process that entails permanently laminating the filter material in between two pieces of optical glass that are ground flat to tolerances of a ten-thousandth of an inch, then mounting them in precision aluminum rings.
