Rian Johnson Taps Knives Out DP Steve Yedlin for RAW iPhone Camera App

Rian Johnson has commissioned Knives Out cinematographer Steve Yedlin to build Chromagraph Camera, an iPhone app that captures RAW and applies the filmmaking team’s own image processing.

The tool hands Johnson’s on-set color science directly to still photographers, collapsing the wall between a phone snapshot and a graded motion-picture frame.

“So I recently badgered my cinematographer Steve Yedlin into making my ideal iPhone still camera app. It shoots RAW, bypasses the iPhone’s look processing and instead uses the same image processing we use on our movies.”, Rian Johnson

Bypassing Apple’s Pipeline: Why the RAW Architecture Matters

Yedlin’s app does not sit on top of the iPhone’s native rendering as a cosmetic layer. Per the cinematographer’s own description, it replaces the phone’s look management outright with processing calibrated to Apple’s camera hardware.

That distinction separates Chromagraph from the filter economy. Most mobile camera apps stack presets over Apple’s baked-in contrast and saturation; this one intercepts the RAW data before any of that happens.

Programmer Eric Cameron collaborated on the build, rounding out a small technical team behind a tool with unusually serious color-science ambitions. The engineering burden sits in matching Yedlin’s film pipeline to sensor output he did not design.

For Johnson, the appeal is continuity. The look he and Yedlin have refined across features becomes a pocket instrument, not a proprietary asset locked inside a color suite.

A Director-DP Partnership That Travels Beyond the Set

Johnson and Yedlin’s collaboration is among the more durable in modern studio filmmaking, spanning his franchise work and the Knives Out mystery series. That partnership now produces consumer software, an unusual lateral move for a director at Johnson’s commercial altitude.

The original Knives Out was financed by MRC and distributed by Lionsgate, with Johnson writing, directing and producing alongside Ram Bergman. It opened November 27, 2019, anchoring the Thanksgiving corridor with a star-heavy ensemble led by Daniel Craig.

That ensemble, Chris Evans, Jamie Lee Curtis, Michael Shannon, Toni Collette, LaKeith Stanfield, Ana de Armas, Don Johnson, Katherine Langford and Christopher Plummer, gave the mystery a marquee density that holiday distributors prize.

Johnson’s profile since has been shaped by Star Wars: The Last Jedi and the continued life of the Benoit Blanc franchise, keeping his name in front of both multiplex crowds and awards voters.

What a Camera App Does for a Filmmaker’s Brand

Chromagraph functions as auteur branding in hardware form. Johnson is effectively selling his visual signature as a downloadable utility, with the pitch line, the same processing used on the movies, doing the marketing work.

That framing carries real weight with the photography and filmmaking audience that follows cinematographers as closely as directors. Yedlin’s reputation among image-makers is the product’s credibility engine.

The app also arrives without a studio release notice, positioning it as an independent side project rather than a franchise tie-in. It should not be read as a signal of a new Knives Out production milestone.

For a filmmaker whose commercial standing rests on theatrical event releases, a low-cost software tool is a cheap, high-visibility touchpoint between features, keeping his craft credentials circulating across our trade entertainment wire desk while the next slate takes shape.

The economics are modest but the positioning is sharp: a paid app built on existing pipeline work converts years of color-science investment into a recurring, low-overhead product line. Contrast that with the heavy marketing spend behind theatrical war releases like contemporary event-film campaigns, and the app’s cost-to-reach ratio looks formidable.

Whether it converts casual iPhone shooters into acolytes is a distribution question. What it already proves is that Johnson and Yedlin treat their image pipeline as portable intellectual property, and they are willing to sell it.
