Special effects cinema filter

The Nisi Cinema 77mm Rotating Allure Streak Blue 2mm filter is a special effects cinema filter designed to render a single light ray from a point source into elongated blue streaks. It uses optical glass with etched lines spaced 2mm apart to create the horizontal streak effect. The rotating front element allows the photographer to adjust the orientation of the streak to match the composition. It is built with an aluminum frame for durability.

For creative cinematography and photography

This filter suits cinematographers and photographers who want to add anamorphic-style blue streak effects to highlights and point light sources. It is not for shooters who need a neutral filter for standard image correction or protection. It does not suit workflows that require a fixed orientation without the ability to rotate the effect. Buyers looking for circular polarisation or neutral density functions should look at different filter types.

77mm thread with rotating front

The filter fits lenses with a 77mm front thread and features a rotating front ring to change the angle of the light streaks. The effect is created by precision-etched lines on optical H-K9L glass. The aluminum frame holds the glass and provides the rotation mechanism. This specific thread size and rotation function determine whether the filter matches the lens and creative control required.

Questions about this item

How do I clean the etched lines on the optical glass without damaging the 2mm spacing?

Use a soft lens brush to remove dust, then apply a few drops of optical cleaning fluid to a microfibre cloth and wipe gently in a circular motion; avoid abrasive materials or excessive pressure on the glass surface.

Will the aluminum frame or rotating mechanism bind after repeated adjustments on set?

The aluminum frame is built for durability and the rotating front operates smoothly like a CPL; regular cleaning of the filter threads prevents grit from causing stiffness during rotation.

Does the filter add noticeable heat or power draw when used under continuous studio lighting all day?

As a passive optical glass filter it draws no power and generates no heat; it simply transmits and modifies light without affecting the thermal load on your lighting setup.
