Apple and Google have finally agreed on something: RAW photography with DNG files. With the launch of iOS 10, Apple adds RAW support to select iOS devices with DNG (iPhone 6S, 6S Plus, SE, 7, 7 Plus, and the 9.7-inch iPad Pro), the same file format many Android users have had access to since the launch of Lollipop 5.0 over a year ago. But what exactly is RAW photography and DNG anyway – and what’s the big deal?
Smartphones traditionally snap the very familiar JPEG file that’s easily (and instantly) shareable. JPEGs are automatically edited and adjusted by the software built into the camera or smartphone so they’re ready to go. The downside is that JPEGs are heavily compressed. RAW file types, such as DNG, on the other hand, are untouched by that automatic software, leaving more of the photo’s data intact. The untouched RAW file, whether opened on a desktop program or a mobile photo editor, offers more flexibility in retouching than a JPEG that’s already been processed. As you might suspect, the tradeoff is that RAW files tend to be very large.
