Any reason to use ProRAW if you never edit photos?
Barely any, it’s basically a toggle where you choose human processing over the “photonic engine” processing of the captured images.
When you switch to proRAW, you’d be getting worse results, since the work being done by the photo processing algorithms would be avoided, hence the RAW naming.
In my mind, the setting could be interesting for occasional use, where you yourself would be post-processing images for a specific photographic shoot (as amateur or pro) or where you’d have some professional process the shots for you.
E.g. Don’t involve a stranger, a professional photographer, in your family event, but have a pro edit the pics together with you in his studio afterwards to get most out of them. Think wedding, family parties, honey moon,…
There are remote services over the globe to process images, it’s a business used by many ‘photographers’. Algorithms are perhaps better, unless you want to apply a very distinct style. In that case I personally would be sitting together with a pro, or grow into the process.
I guess it’s safe to say that algorithms’ help is most suitable for the vast majority of people. ProRAW really is for pro’s or pro involvement.
