I’ll be honest, I wasn’t entirely sure what to expect when I first tried the K&F Concept Colorful Streak Filter. At first, the results weren’t quite what I had in mind, but after a bit of experimenting and research, I realised this filter really comes into its own when you line up your composition with a strong, direct light source. Think neon signs, street lamps, candles, and even car headlights. Pretty much like the Star Filters I also tried out.

Please Note: While K&F CONCEPT sent me these filters for review, all thoughts and opinions are my own.

Unlike star filters that break the light into multiple points, this one stretches highlights into bold, colourful streaks. It feels straight out of a music video or stylized film and adds instant atmosphere. Closing down the aperture to around f/16 or smaller really helps intensify the effect. And if you’re in Aperture Priority mode, keep in mind that using negative exposure compensation doesn’t enhance the look—it actually diminishes it.

This filter isn’t about subtle enhancement; it’s about creating dreamy, cinematic drama. For night street photography, live gigs, or even Christmas lights, it would transform the ordinary into something surreal and striking. The filter can also be rotated, letting you change the angle of the streaks for even more creative control.
