Rian Johnson and Steve Yedlin bring cinematic color processing to iPhone with Chromagraph Camera

Director Rian Johnson and cinematographer Steve Yedlin have launched Chromagraph Camera, an iPhone app designed to bring the custom color science used on films like Knives Out to mobile photography. The app is available on the App Store for $12.99 with no in-app purchases, while WIRED reports the price as $13 dollars. [1][2]

Instead of applying a standard filter over Apple's default image processing, the software works directly from raw image data to build the picture using proprietary color mathematics. Users frame shots normally and review the applied film-like styling in the app gallery afterward. The platform retains full-quality raw files, lets users tweak exposure, color, grain, and halation, and supports automatic exports to the system photo library as JPEG or HEIC files. It already supports the iPhone Duo, though early feedback notes its interface could use fine-tuning. [1][2]

Johnson said he initially commissioned Yedlin and color science developer Eric Cameron to build the tool for his personal photography before releasing it publicly. The launch comes amid growing user interest in third-party camera apps, such as Halide, that bypass Apple's increasingly aggressive computational processing, quickly propelling Chromagraph Camera to the top paid spot in the App Store's Photo & Video category.
