The Schneider 6.6x6.6" 1mm Clear 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 6.6 x 6.6" 1mm Clear 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 no color, instead of the blue highlights generated when using traditional anamorphic optics that are not designed to suppress streaking. Clear True-Streak Filters allow existing colors or lack of colors displayed by point light sources to be maintained, while True-Streak Filters that are formulated to create red, orange, yellow, green, blue, pink, or violet banding are also available.

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.

A: They are polypropylene and are acid free and archival.

Q: 5. My hygrometer gauge went below the optimal level, is that okay? There are no instructions or guidelines with the documentation regarding this topic.

A: Do not understand “below optimal level” because any reading on the green zone is optimal.

Q: 6. Does "set of four" mean that I'll get 4 male and 4 female?

A: This set gives you 4 male clips and 4 female receivers.

A: This is made to safeguard against debris, sand, and water while shooting in the elements or inclement weather.

Q: 8. Will this work with my Canon RF 70-200mm f/2.8 lens?

A: Yes, the Canon 70-200mm f2.8 RF mount lens uses any 77mm filter.

Q: 9. Would this hold a Nikon 200-500 lens??

A: Yes, but it is a tight fit - the lens would need to be positioned at an angle.

Q: 10. Can we put Cannon 5dMkiii with 24-105 lense and 70-200 lense in this box?

A: Yes, however, we recommend that you consider the Ruggard PDC24-BBS Portable Dry Case with a Dehumidifier & Fabric Insert 22.4 Liter, since this case contains fabric inserts that will better accommodate and protect your camera and lenses. https://www.bhphotovideo.com/c/product/1377861-REG/ruggard_pdc24_bbs_portable_dry_case_24.html
