NiSi Cinema Rotating 82mm Allure Streak BLUE（2mm 光條）

Finally a streak filter that gives me actual blue streaks instead of just a washed-out tint. The 2mm etched lines are precise enough to keep the highlight crisp while still blooming nicely.

The rotating ring makes dialing in the exact angle of the blue streak effortless, and the glass itself feels precision-made. It gives my night shots a clean, cinematic single light ray without any weird flare or ghosting. Exactly the look I was after for building scenes.

Getting that streak effect exactly horizontal or vertical is so satisfying with those distinct click stops. The blue tint feels subtle on normal lights but really pops when you catch a car headlight at the right angle.
