Chromagraph Camera: Rian Johnson and Steve Yedlin Launch $13 iPhone App for Film-Grade Color

Key points

• Chromagraph Camera is a $12.99 one-time purchase app for iPhone that processes raw image data using custom color math developed by cinematographer Steve Yedlin.
• The app bypasses Apple’s default computational photography, instead applying a look similar to that used in Rian Johnson’s films, such as 'Knives Out' and 'The Last Jedi.'
• It became the top paid app in the iOS Photo & Video category shortly after Johnson announced it on X in late October 2026.
• The app includes post-capture adjustment tools for color, tone, texture, exposure, grain, and halation, but does not support video or Android devices.
• Yedlin emphasizes that the app is not a filter but a distinct processing pipeline, aiming for an 'artful' rather than clinically correct image.

Background

This launch follows a period of increased interest in third-party camera apps that offer more control over iPhone image processing, such as Halide’s Mark III. The app’s development is rooted in Yedlin’s two decades of collaboration with Johnson, during which he refined color science for cinema cameras like the Arri ALEXA. The project began as a personal tool for Johnson but was expanded for public release after testing over ten weeks. The app’s success highlights a growing consumer desire for customized, film-inspired aesthetics in smartphone photography, distinct from the heavy-handed computational processing often associated with Apple’s default camera.

How outlets are covering it

IndieWire highlights the technical depth of Yedlin’s color science, noting that the app uses entirely different math from standard iPhone processing to achieve a look that is aesthetically pleasing rather than photometrically correct. WIRED emphasizes the app’s viral popularity and its one-time fee of $13, noting that it quickly became the top paid download in the iOS store. Deadline focuses on the collaboration between Johnson and Yedlin, quoting Johnson’s description of the app as an 'elegant one-stop-shop' that uses the same image processing as their movies. 9to5Mac provides technical details, noting that the app supports the iPhone Duo and stores full-quality raw files, while also mentioning that some users found the adapted interface needed fine-tuning. All sources agree that the app is exclusive to iOS and currently limited to still photography, with no plans for Android or video support.

Why it matters

The launch of Chromagraph Camera represents a significant intersection of Hollywood filmmaking and consumer technology, offering users a direct link to the color science of major films. Its rapid ascent to the top of the App Store charts indicates strong consumer demand for customized, film-inspired photography that moves beyond standard computational processing. The app’s success also underscores the growing influence of film professionals in shaping consumer tech trends, as well as the potential for niche, high-quality apps to disrupt the market dominated by larger, more generic photography tools.

What to watch

The team behind Chromagraph Camera has stated that they do not plan to release an Android version or add video support in the near future. The app’s developers are focused on refining the current iOS experience, with Yedlin noting that the process of creating the app was intense but ultimately satisfying. Future updates may include additional tools or refinements to the existing color and texture adjustments, but the core focus remains on maintaining the curated, artful look that defines the app. The team has also expressed interest in supporting video in the long term, though this is not a priority for the current release.
