Rian Johnson's Chromagraph camera app brings film colour to iPhone photos

Film director Rian Johnson, known for the "Knives Out" mysteries, has launched Chromagraph Camera, a paid iPhone camera app that makes photos look like the images in his films. Johnson announced the app on X on October 28, 2026. It was built by his longtime cinematographer Steve Yedlin and colour-science programmer Eric Cameron, and it uses the colour science Yedlin developed for Johnson's films, adapted for the iPhone. The camera app costs $12.99 as a one-time purchase, with no in-app purchases, needs iOS 17 or later and is available only for iPhone. Within days it was reported to be the top paid app in the App Store's Photo and Video category.

Every smartphone photo goes through automatic processing: the phone adjusts brightness, sharpens edges, smooths noise and boosts colours to produce a pleasing picture instantly. That processing is why phone photos look clean, but also why many of them look alike. Chromagraph takes a different route. By starting from RAW data, the unprocessed information from the camera sensor, and applying a look designed for cinema, it gives users more control over the final image and a style that does not resemble the standard phone look.

The story behind the app is part of its appeal. Johnson has said he first asked Yedlin and Cameron to build it for his own use, and the team then decided to release it to everyone. That gives ordinary users access to the same colour thinking used on big-screen films. For young photographers and content creators, tools like this lower the barrier to a distinctive visual style, which matters in a crowded feed where looking different is half the battle.

There are limits. The app's look is deliberate, and reviewers note that it may not suit every photographer. It handles still photos only for now, and Android users are left out. RAW files are also larger than ordinary photos, which can fill a phone's storage faster. And because the app hands more decisions to the photographer, users who want the best results will need to learn basic controls such as exposure and colour balance.

For creators in India, the launch is part of a wider trend: filmmakers and artists turning their personal tools into apps. It also shows why understanding the basics of colour and light, not just filters, is becoming a useful skill for anyone building an audience online.

Short-term: Chromagraph's early chart success will draw more attention to camera apps that offer a distinctive, cinema-inspired look, and to RAW photography on phones.

Long-term: If such apps keep finding audiences, more filmmakers and cinematographers may release their own tools, and phone makers may face more pressure to offer users control over how photos are processed.

Who is affected: iPhone photographers and content creators; filmmakers and cinematographers; app developers in the photo and video category; and Android users, who cannot use the app for now.
