title: "Anamorphic Streak Flare"
description: "A drifting field of bright points, each one throwing the long horizontal blue-violet streak a real anamorphic cinema lens produces. Built from the measured filter constants: a 0.3 high-pass, 80 horizontal taps at quarter resolution, a samples/3 gain and a 0x7a8aff tint."
