With the release of iOS 14.3, the iPhone 12 Pro and 12 Pro Max get Apple’s new raw photo format called ProRaw. The new file lets you have the customization of a raw file built atop the iPhone’s computational photo smarts. For the past few weeks, I’ve been testing out the new feature and I’m impressed at how ProRaw transformed my phone photography.

ProRaw photos can be taken using the default Camera app. Next, ProRaw files are large. For example, I took a photo of the same subject using each file format on the iPhone 12 Pro Max. The HEIC file was 5.2 megabytes, the JPEG was 6.8MB, the raw photo (taken with the Moment app) was 16.5MB and the ProRaw photo was…
