Rian Johnson launches Chromagraph Camera app for iPhone
The US$12.99 app offers custom image processing associated with the ‘Knives Out’ films and has no in-app purchases.
Director Rian Johnson has introduced Chromagraph Camera, an iPhone photography app that promises to use image-processing methods from his “Knives Out” films. The app costs US$12.99 and is available without in-app purchases.
According to its App Store description, Chromagraph processes raw image data using its own methods rather than adding a filter after the phone’s standard processing. Users compose a photograph in the viewfinder, then open the gallery after capture to see the processed result.
The app’s listing says it retains full-quality raw files and displays them with its processing and users’ adjustments applied. Photos can be exported as smaller files for sharing or saved to the photo library. An automatic export option saves processed images in JPEG or HEIC format.
Johnson said on X that he initially asked cinematographer Steve Yedlin and color science developer Eric Cameron to build the app for his own use before they decided to offer it publicly. He said he wanted a streamlined combination of custom processing and controls for color, exposure, grain and halation after trying other third-party camera apps.
