The Hollywood Color Nerd Who Shot ‘Knives Out’ Explains His Viral iPhone Camera App
Cinematographer Steve Yedlin, known for films including *Knives Out* and *Star Wars: The Last Jedi*, has launched Chromagraph Camera, an iPhone app that applies his distinctive approach to colour and image processing. It quickly became the iOS store’s top paid download after director Rian Johnson promoted it, reflecting interest in a deliberately stylised alternative to the iPhone’s default camera look.
The app captures RAW image data and processes it after the photo is taken, adding tailored tones, colour and grain; users can then adjust exposure and texture. It costs $13 as a one-off purchase and currently takes still photos only. Yedlin and Johnson developed it with programmer Eric Cameron, while Yedlin cautions that software cannot remove the iPhone’s hardware limits and says the app offers a specific artistic interpretation rather than a neutral or professional camera replacement.
In short
- Steve Yedlin’s iPhone camera app quickly topped paid downloads.
- Chromagraph applies his film image processing to still photos.
- The $13 app offers a stylised look, within phone hardware limits.
Explained simply
Steve Yedlin is a cinematographer, the person responsible for how a film is lit and how its images look. He has worked on films including Knives Out and Star Wars: The Last Jedi, often using colour and image processing to create a carefully chosen visual style.
An iPhone camera records an image using both its lens and software, which shapes the colours and detail people see. Chromagraph Camera is designed to give photos a particular look after capture, drawing on Yedlin’s approach; it was developed with director Rian Johnson and programmer Eric Cameron.
