Learn how to use the NiSi Allure-Streak Blue Filter with the IP-A system to add anamorphic-style blue streaks to your iPhone photos and videos.
Quick answer
The NiSi Allure-Streak Blue Filter for the IP-A system creates horizontal blue streaks from point light sources, mimicking anamorphic lens effects on your iPhone.
Understanding the effect
This filter is designed to add a single, elongated blue streak horizontally from any bright point light in your frame. It’s a creative tool, not a correction filter, so it works best when you have intentional light sources like street lamps, car headlights, or reflections.
Rotation is key
The filter can be rotated to change the angle of the streak. This means you’re not stuck with a horizontal-only look—tilting the filter can create diagonal streaks for more dynamic compositions.
How to use the NiSi Allure-Streak Blue Filter
- Attach the IP-A holder: Mount the NiSi IP-A Filter Holder onto your iPhone. Ensure it’s securely clipped and centered over the lens. A loose holder can cause light leaks or uneven streaks.
- Insert the Allure-Streak Blue Filter: Slide the filter into the holder’s slot until it clicks into place. The filter should sit flat and flush. If the filter is crooked, the streak angle will be inconsistent.
- Compose your shot with a point light source: Look for a bright, small light source in the frame—like a streetlamp, car headlight, or reflection. The filter will turn that light into a blue streak. The streak is only visible from point light sources; diffuse light won’t produce the effect.
- Rotate the filter to adjust streak angle: Gently rotate the front ring of the filter to change the streak’s orientation from horizontal to diagonal or vertical. Rotating too quickly can shift the filter out of alignment; do it slowly while watching the live view.
- Shoot and review: Take a photo or record video. Check the streak’s color and length. The blue streak should be clean and not overpower the rest of the image. If the streak looks too faint, try a brighter light source or reduce ambient light.
