Austin Mann, on iPhone ProRAW →

The photographer:

It’s important to understand ProRAW and when to use it. ProRAW is not simply a magic switch you can flip on to make your photos better. In fact, the non-ProRAW file initially looks much better than the ProRAW file, so shooting ProRAW really only makes sense if you intend to spend the time fine-tuning the image in post.

I suggest turning on ProRAW when you are shooting in extreme conditions of any kinds (extremely low light, extremely high dynamic range with super bright highlights and dark shadows, mixed light temperatures, and so on). Also, use ProRAW if you plan on enlarging the images (on screen or in print).
