The Schneider 4x5.65" 1mm 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" 1mm 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 1mm apart from each other. True-Streak Filters with spaces of 4mm, 3mm, or 2mm 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.

Q: 5. How are these compared to the Rokinon Xeen?

A: Cine lenses such as the Schneider Xenon and Rokinon Xeen share the attributes that are so needed in prime lens sets for movie production. Principally these are consistent physical size and consistent image quality. Inconsistent size slows down production and inconsistent image quality slows down post-production with a possible affect of the viewing experience. What differentiates the two brands essentially is that the Xeens are good quality while the Xenons are even better. If the budget is limited, go with the Xeens confident that you will get good results. If the budget is more generous, go with the Xenons. What you will get is superb design, build and image quality that you can feel and see. The Xenons will last for years in hard, 18 hour a day movie production.

Q: 10. Is there a choice of grey or green? You list both in the color description... the photo shows green, and the response to a question about color indicates they are grey. Is it luck of the draw? This treatment is puzzling.

A: Domke makes many products that are their own signature dark grey with some green in it. You can search for "Domke" and "gray/green" on our website to see many others. They call the color "gray/green." Except in especially bright light, I believe many people would think of it as more gray than green, and so do I. However, with powerful strobes being used for product photos it can appear a bit lighter than it would otherwise. In sum, I'd call it grey with sort of green color cast; Definitely more gray than green to my eyes.
