Rian Johnson’s New iPhone App Chromagraph Camera Uses Knives Out Cinematographer Steve Yedlin’s Signature Image Processing

Acclaimed filmmaker Rian Johnson has teamed up with his longtime cinematographer Steve Yedlin to launch Chromagraph Camera, an iPhone app that brings the duo’s cinematic color science and image processing to everyday shooters. Johnson, the two-time Oscar-nominated writer-director behind Knives Out and Brick, announced the app this week, explaining it “uses the same image processing we use” on their feature films. Yedlin, known for his meticulous approach to digital color, developed the app’s RAW processing pipeline to mimic the look of their collaborations. Chromagraph Camera targets photographers and filmmakers who want a more filmic, controlled aesthetic without complex post-production. The app’s launch highlights a growing trend of Hollywood talent packaging proprietary tools for consumer use, democratizing high-end looks. For Johnson and Yedlin, it’s a natural extension of their nearly three-decade partnership. The tool could reshape how mobile creators approach color and tone, making professional-grade processing accessible to anyone with an iPhone.
