The NiSi Cinema Rotating 72mm Allure Streak Orange (2mm) is a special effect filter that reproduces a single beam of light from a point light source. This filter features a series of etched lines that run across the filter surface at a distance of 2 mm apart. The filter creates the effect of elongated orange streaks that radiate horizontally from the light source and are typically seen when using an anamorphic lens. The 72mm filter has a rotating front, similar to a CPL. When the filter is rotated, the orientation of the light beam can be adjusted to fit the composition or desired effect. The filter is made from clear optical glass H-K9L for consistent image clarity and has an aluminum frame.
