The Schneider 4x5.65" 4mm 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 4 x 5.65" 4mm 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, instead of the blue highlights generated when using traditional anamorphic optics that are not designed to suppress 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 4mm apart from each other. True-Streak Filters with spaces of 3mm, 2mm, 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.

Related Questions and Answers

Q: 1. How does it compare to B+W Vario ND 1-5? What is the front size? B+W's front size is designed at 86mm for less vignette. Even so, I did find vigenette at 24mm on my 24-105 lens. How about the color shifting? B+W is shifting green on 1-3 stops.

A: The front filter thread of this filter is 82mm. Most filters will begin to vignette to some degree at 24mm. Color shift is nearly always present when using variable ND filters, but how much varies between filters.

Q: 2. Does the front thread turn when adjusting the ND level or stay static?

A: Yes, the front ring rotates when adjusting ND on the Schneider True-Match Vari-ND MKII Variable Neutral Density Filter (82mm).

Q: 3. Can I use it with a digital cinema camera? I use blackmagic ursa mini 4k (and don't usually use the autofocus) or should i get the circular one?

A: I use it on my Red Dragon when I use my bright tangerine clip on matte box. It works fine. But, I also have a circular polarizer for my bigger matte box.

Q: 4. What is the thickness 2mm or 4mm?

A: This filter is 4mm thick.

Q: 5. To figure out the size of the push-on lens cap - what is the OD of the filter?

A: any filter size plus 3mm

Q: 6. The overview for this Variable ND filter states that the effect is achieved by "...stacking highly neutral gray polarizing filters..." If so, will this filter also work as a good polarizing filter? I need a polarizer + ND filter for waterfall photography, so I was wondering whether a separate polarizing filter is needed in combination with this filter.

A: The Schneider True-Match Vari-ND MKII Variable Neutral Density Filter (82mm) does not act as a Polarizing Filter. A separate Polarizing Filter is necessary to get the Polarizing effect.

Q: 7. Do these work basically other streak filters, but the color of streaks depends on the light source? Unlike the other one-color filters that have the same streak color always?

A: Correct the Vaxis VFX 95mm Streak Filter for Tilta Mirage Matte Box (Rainbow) works like the other streak filters. The fitter will give different effects depending on the light source but more how you rotate the filter.

Q: 8. Schneider 4 x 4 Five Slot Filter Pouch can I put Lee seven5 filters in this pouch?

A: Hi Albert,it is perfect for Lee seven5 filters. I use it for the Lee 100mm System.

Q: 9. Can BH please add some images/ video of what the flare actually looks like?

A: In use image examples for the Moment CineFlare Gold Streak Filter can be found at this link: https://bhpho.to/4gWI0SI

Q: 10. Is there any light loss with these filters?

A: From testing in the store, we saw no visible change in exposure, likely indicating a 1x filter factor and almost complete light transmission (minus any potential loss from coatings and glimmerglass particulates).
