I ordered it, I did the beta when they had that for Windows but it was limited in features, a lot were there but a huge amount was left out. It seemed ok, and for the price it will be probably worth getting. But it is just another workflow. Most software today uses DCRAW for conversion at some point under the hood, or at least most of them do. So it comes down to the after conversion editing. Luminar is supposed to work with most PS plugins, so those will still be available in theory. It is another tool for the toolbox. There is also Topaz Studio, On1 Photo Raw, etc. Currently most of them have issues to work out, and I am sure Luminar will as well.
