I have mixed feelings about Luminar. I appreciate them trying to break out and do something different. I think algorithm driven image developing is here to stay (ie., all cell phone images go through this).
For me image processing is an ecosystem to include culling, sorting, developing, and sharing. Also includes mobile capture, mobiel processing, syncing across platforms. Some of this I do in batches -- a travel image set or a family event. I use Collections a lot in Lightroom. I share often to Zenfolo and sometimes to Adobe Portfolio. I have tried Photomechanic for a while when LR loading used to be so slow. Sometimes I spend a lot of time on one photo, but more often I am working through a batch and trying to balance a limited amount of time with a larger set of images (100-300 or more).
So for me, Luminar Neo has to fit into the whole thing. Luminar (or any product) as a Lightroom plugin never is smooth. LR converts to a large TIFF, then opens Luminar, then you edit, then it closes Luminar (so for each photo you get an open and close).
So while I want to try LR alternatives, I feel locked in not by the program but by the ecosystem.
