The Knives Out camera app has a catch worth knowing: shoot first, see the look after.

Update — November 1, 2026: The U.S. App Store listing now shows version 1.2.0, including Archive export/import, a default-lens option and an option to turn off macro mode. These are developer-listed changes, not features we have tested. The capture-and-export explanation below remains relevant; check the installed version before following it. This note was added before the story’s scheduled release.

A connection to Knives Out makes a camera app easy to notice. The more useful question is whether you want its way of taking a photograph.

Chromagraph Camera surfaced in 9to5Mac’s October 30 report about director Rian Johnson’s involvement. It is already available: the U.S. App Store history lists version 1.0 on October 20 and an October 23 update adding iPhone Duo support. This is a closer look at a newly noticed app, not a claim that it launched this morning.

You see the finished look after the shutter

Developer Chromatic Applications says cinematographer Steve Yedlin designed its color and texture rendering, using the processing approach associated with the Knives Out films. The app starts with raw image data and applies its own rendering.

The workflow detail matters: you frame the photograph, take it, then open the gallery to see the finished look. It is not presented as a live preview of the final result. That could appeal to someone who enjoys making an image and then seeing what it becomes. It may be less appealing when you want the preview to settle every choice before pressing the shutter.

We have not used the app, so there is no image-quality verdict here. A famous film connection cannot establish how it handles your kitchen lighting or a moving pet.

The export is part of the photograph

The developer says the gallery keeps full-quality raw originals while displaying the look and your adjustments. You can adjust color, tone and texture, then share smaller rendered files. Optional automatic export sends JPEG or HEIC copies to the photo library.

If you decide to try it, our suggestion is a small comparison: photograph the same familiar scene with your usual camera app, then inspect both exports where you normally view or share pictures. Look at the subject, bright areas and colors you recognize. Judge the version you will actually keep, rather than a promotional screenshot.

Check the listing on your own device

The U.S. listing is $12.99 and specifies iOS 17 or later for iPhone. It also lists iPadOS 17 and watchOS 10 compatibility, an English interface and Family Sharing. Those entries do not establish identical functions on every device. Use your own regional listing for pricing and compatibility.

The purchase question is simple enough: does the delayed reveal and editing workflow sound enjoyable? If your current camera already gives you photographs you like, a filmmaker’s preferred rendering is an interesting option, not an obligation to replace it.
