Chromagraph Camera iPhone App
Knives Out director Rian Johnson wanted iPhone photos that look like his movies, so he and cinematographer Steve Yedlin built Chromagraph Camera. The app applies the color science Yedlin has refined for 20 years to raw photos, adding contrast, grain and halation in a curve modeled on classic film stocks, and sliders allow you to adjust to optimize for your photo's needs. On Pro iPhones the app requests Apple's ProRAW, while the pair wrote their own burst-merge to cut noise on non-Pro models. The interface stays as simple as Apple's stock camera app, built for quick point-and-shoot photos, and it shoots stills only.
