If you use an iPhone 6s, iPhone 6s Plus or iPhone SE for photography and want the flexibility of capturing RAW files, you're going to want to update your iOS device to Apple's newest operating system iOS 10, which is available today, then grab the latest version of Lightroom for iOS, version 2.5.
New in iOS 10 is support for RAW files, and Adobe is ready with support for DNG. Using Lightroom for iOS 2.5's built-in camera, you can capture and edit DNG files. "Having a true end-to-end raw workflow, powered by DNG and Lightroom, on your iPhone and iPad makes it possible to create absolutely stunning photos that, until a few years ago, could only have been done with a traditional camera," Josh Haftel wrote on the Adobe blog, announcing the new feature.
This capability is only possible with iOS devices that have a 12MP sensor. This includes the iPhone 6s, iPhone 6s Plus or iPhone SE, 9.7-inch iPad Pro and the iPhone 7 and iPhone 7 Plus which will be available starting this Friday.
Also included in this update is support for the cinematic DCI P3 color space introduced by Apple in the 9.7-inch iPad Pro and also included in the new iPhone 7 models, which offers an expanded color gamut that's 25% great than the sRGB color space.
