What Is Apple’s ProRAW Photo Format on iPhone? Justin Duino The iPhone 12 Pro and Pro Max are the first iPhones to support ProRAW, Apple’s take on the RAW image format. In professional photography, RAW files are a must for getting the most out of your images—but what does it mean for the iPhone? What Is ProRAW? ProRAW is Apple’s implementation of the RAW image format, available on the iPhone 12 Pro, iPhone 12 Pro Max, and likely on future iPhones. The RAW format is commonly found on mid-to-high-end cameras, allowing photographers to capture as much information in a scene as possible. Whereas lossy formats like JPEG and HEIF will discard “unnecessary” information when you squeeze the shutter, RAW formats hold on to most of it.
