Key Points:

Hollywood director Rian Johnson has launched Chromagraph Camera, an iPhone app developed with cinematographer Steve Yedlin that applies the same image processing techniques used in the 'Knives Out' films.
Chromagraph Camera processes raw image data uniquely, offering a film-like experience where users see the finished look only after taking a photo, with customizable tools for color, tone, and texture adjustments.
The app is available for $12.99 with no in-app purchases, supports iPhone Duo, and stores full-quality raw files alongside edited versions, emphasizing that it is not a filter but a distinct image processing method.
Johnson revealed that the app was initially created for his personal use to achieve a streamlined solution combining custom image processing and editing tools, before deciding to release it publicly.
Currently the top paid app in the App Store's Photo & Video category, Chromagraph Camera provides an alternative to Apple's default computational photography with a curated cinematic look.
