The Schneider 77mm Green True-Streak Filteris designed to be used perpendicular to a point light source such as the sun, a light bulb, or a candle. Within the filter's glass is a combination of fine line types whose action is limited to point light sources. Upon those light sources, those lines create the effect of a scene or image that has been recorded with an anamorphic lens and then displayed using a complementary reverse projection lens. This can result in prominent, elongated streaks that are symmetric and extend horizontally from each point light source for the purpose of drawing attention to a specific part of the frame, or to create a visually dramatic effect.

If an image or footage is captured with an anamorphic lens for the primary purpose of obtaining a greater aspect ratio than what is possible when only using spherical lenses on a 35mm format, the direct result will appear compressed and distorted. Projecting this compressed and distorted footage or imagery through a reverse anamorphic projection lens allows elements within the scene to be viewed in their correct proportions. A complementary effect of this process after it is completed is the creation of elongated, blue-colored, horizontally symmetrical highlights from point light sources that can extend through the frame.

Many cinematographers and photographers find this effect desirable and the Schneider 77mm Self-Rotating 2mm Green True-Streak Filter is intended to allow such highlights to be easily reproduced when using optics that do not have an anamorphic design. This filter renders the streaks it helps to create with a green hue, which further emulates the character of highlights generated when using traditional anamorphic optics that are not designed to suppress colored streaking. True-Streak Filters that are formulated to create red, orange, yellow, blue, pink, or violet banding instead of green are also available, as well as Clear True-Streak Filters that can allow existing colors or lack of colors displayed by point light sources to be maintained.

The line types within this filter's glass are placed 2mm apart from each other. True-Streak Filters with spaces of 4mm, 3mm, or 1mm between their lines are also available where this filter type's effect becomes progressively stronger as the spacing between those lines is decreased.

This filter is most effective for pictures where the light source used to generate the streak effect is a highlight with a significant degree of contrast from the rest of the image. It is constructed from water white glass for clarity as well as color fidelity, and features a brass filter ring that can be rotated in order to adjust the overall orientation of the streak effect.

Q: 3. Can you confirm the threading on this filter?Is it 138mm diameter with 1mm pitch?How deep is the overall thread?What is the overall thickness of the filter? (or more importantly the thickness excluding the rear thread)Unfortunately the manufacturer lists very minimal information on their website and I can't find any detailed pictures to deduce the important dimensions from.

A: It is a 138 mm diameter but there are no threads on this filter. I use it in the rear dounut of a matte box.

Q: 8. Will this work with the ARRI K2.66128.0 F4 Filter Frame (for ARRI MMB 2)?

A: No, the Schneider 138mm Circular True-Polarizing Water White Glass Filter (B&H# SCCP138) is a 138mm (5.43") diameter filter whereas the ARRI Filter Frame Combo 4 x 4"/4.5" Round (B&H# ARK2.66128.0) (which you are referring to by its manufacturer model number of K2.66128.0) only accepts certain filters up to 4.5" in size.

Q: 9. Does rotating the filter change it’s effect?

A: Yes, you insert the filter in a holder and rotate the holder to achieve the desired effect, ie; removing reflections from glass or water as well as saturating colors, etc...

Q: 10. Multi coated on the filter for Anti-Reflective?

A: This filter does feature anti-reflection multicoating.
