I too started with PhotoShop early on, 1.x something. Used Lightroom for a week or so but stayed with the heavy weight PS. Yet, I was late arriving to the complete digital camera/processing realm, sticking with film and scanning to digital format for post processing when not using the dark room. The greatly increasing cost of chemicals for soup was the final motivator.
When the monthly subscription based, cloud storage, app appeared, I was completely turned off. I want to buy once and be done. And anything cloud has never appealed to me. I guess I'm too old, the son of a Depression (the Big One) child, so I like to own outright and keep my stuff close at hand.
I stayed with the monthly subscription until Luminar 4 was released. 4 updated 3 to include cataloging and a host of other features. No, Luminar 4 can't touch PS, but, I do like the features it affords me. There are some shortcomings with the current version that the developers are aware of and hopefully fix with the next update. The one fix I want to see will be invoking CA correction for batch processing images. Currently, you have to wade through the menu tree for each image edited, a royal pain if working with a large batch!.
Leica saves in DNG format and no issues working with the files in Luminar 4.
