I did try to upload an RAF file but of course it was too large! Cos I don't do Dropbox or the like! Of the treatments shown, I prefer Danial's version.
I normally use Lightroom and occasionally Photo Ninja, and of course Apple has not got around to recognising X-T2 RAF files yet but I expect they will eventually get around to it??? I download RAF and JPEG files into a folder in Finder, which shows the files but not a RAW thumbnail, and thence into Lightroom. Lightroom sees the RAF files no problems! I assume that Lightroom is ACR with a few bells and whistles added on, and am pleased with the output that I see, which on a Retina screen are pretty good! when the files are uploaded to the forums I subscribe to there is a substantial degradation to what I see, I assume this effect is down to the forum software doing things to the files for display reasons! this is not a complaint but an observation!
When I moved to Fuji I already had Lr so I just carried on using it, at first the Program was not good to RAF files but after a couple of updates it is much improved.
