Rian Johnson Built His Own iPhone Camera App to Bring Cinematic Style to Smartphone Photography
The director wanted to translate the look of his films into his iPhone photos—and let everyone else try it too.

A Director's Vision, Now in Your Pocket
Rian Johnson, the filmmaker behind Knives Out, Glass Onion, and Star Wars: The Last Jedi, has long been known for his distinctive visual style. But when it came to capturing everyday moments on his iPhone, he found the built-in camera app lacking. So he did what any resourceful technologist would do: he built his own.
In a recent interview, Johnson explained that the default iPhone camera app, while powerful, doesn't offer the granular control over color, contrast, and grain that he relies on in his film work. "I wanted my phone photos to feel like they came from the same world as my movies," he said. The result is a custom camera app that applies a proprietary set of image processing filters designed to mimic the look of his cinematography—complete with film-inspired color grading and subtle texture.
From Set to Smartphone
Johnson's app isn't just a vanity project. He's made it available to the public, allowing photography enthusiasts to experiment with the same presets he uses. The app offers a range of adjustable parameters, including temperature, tint, and film grain intensity, giving users a taste of professional-grade color grading on a mobile device.
This move reflects a broader trend in 2026: creatives are increasingly turning to custom software to achieve unique aesthetics that off-the-shelf apps can't provide. With smartphone cameras now capable of shooting in RAW and ProRAW formats, and with computational photography advancing rapidly, the gap between mobile and traditional cinema cameras is narrower than ever. Johnson's app taps into that potential, offering a bridge between the casual snap and the cinematic frame.
Why Build Instead of Buy?
When asked why he didn't simply use one of the many third-party camera apps available, Johnson explained that none offered the exact combination of controls and processing he wanted. "I needed something that felt like an extension of my eye," he said. "The built-in app is great for quick shots, but when I want to compose a scene, I need to shape the light and color in real time."
His custom app includes a live preview of the final image processing, allowing users to see the effect before they press the shutter. It also supports manual focus and exposure, and can shoot in both JPEG and HEIF formats.
A Growing Ecosystem of Creator Tools
Johnson's foray into app development is part of a larger movement. In 2025 and 2026, we've seen a surge in creator-built tools—from custom LUTs for video to AI-assisted composition aids. Apple's recent iOS updates have made it easier for developers to access the camera pipeline, enabling more sophisticated third-party apps. Johnson's app, while niche, demonstrates the creative potential unlocked by these APIs.
For now, the app is available for free on the App Store, with an optional subscription for advanced features. Johnson says he has no plans to become a full-time app developer, but he's enjoying the process. "It's a labor of love," he said. "And if it helps someone else tell their story, even better."
