Rian Johnson launches Chromagraph Camera app for iPhone

Film director Rian Johnson, known for the “Knives Out” series, has released a new iPhone camera application called Chromagraph Camera. Developed alongside cinematographer Steve Yedlin and programmer Eric Cameron, the app aims to replicate the specific cinematic image processing used in Johnson’s films.

Unlike standard mobile photography apps that apply filters over processed images, Chromagraph Camera works directly from RAW sensor data. This approach bypasses the iPhone’s default sharpening and noise reduction algorithms to control color, contrast, grain, and halation. The app mimics film camera logic, where users view the processed results in a gallery after shooting rather than seeing the final look in the viewfinder.

The application is available on the Apple App Store for a one-time purchase of $12.99 in the United States and 2,000 yen in Japan. It supports iOS 17.0 or later and is compatible with iPhone, iPad, and Apple Watch. While currently exclusive to Apple platforms, the app allows users to export processed images as JPEG or HEIC files while retaining the original RAW data for future adjustments.
