The Schneider 4x5.65" 2mm Violet 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" 2mm Violet 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 violet 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, green, blue, or pink banding instead of violet 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.

Q: 3. How soft is the interior lining? Any concerns about scratching the filters?

A: The interior of this pouch is a soft nylon fabric. I have used this pouch on two, multi-day, trips and have had no scratching problems.

Q: 4. Does the pouch slide on the backpack belt after its attached to the belt?

A: The Ruggard 4-Pocket Filter Pouch (Up to 86mm) has Touch-Tab Belt Loop. So it can slide once on a belt?

Q: 5. Do you think it would be possible to cram two B+W Plastic Filter Case D's (MFR # 65-1071524) inside it (so that it has extra dust/scratch protection in the plastic case, and additional padding protection from the Ruggard Pouch)?

A: I'm going to say probably not. Looking at the specs of the plastic case, and the way this pouch is made, I highly doubt even one would fit. This pouch has 4 slots tat hold up to 82mm, but the slot dividers are stitched together, then stitched inside the pouch, making it a snug fit just for filters. I took a photo to show you, but I don't know how to post it.

Q: 6. Hi! Could you please tell me what the diameter of the front and rear elements of this lens are? Close approximations are fine! Thank you!

Q: 7. Do these have to be used with signatures or can we use third party lenses like cooke optics?

A: The ARRI Impression V Filter Kit is designed specifically to work with Arri ARRI Signature prime or zoom lenses.

Q: 8. does this have fingerprint sensor?

A: No, it does not have a fingerprint sensor.

Q: 9. Can I stick a filter without a lid in this? Or can it get scratched?

A: Yes, you can. There are soft dividers on the inside separating the filters, so you can put them inside without a hard case.

Q: 10. What is the best enlarger lens to print 35mm negatives on a Beseler 4x5 enlarger?
