I am finding this thread interesting in regard to what possible alternatives there are and the potentialities of those available.
I have liked Lightroom but as a perpetual license user on version 6 I do like the cc route it is now going.
I now rely on the DAM function but note for example Luminar mentions being used as a plugin for LR for the image editing.
Approx 90+%of my editing is done in LR with some final sharpening in PS........ therefore if an/any LR alternative offers me a good way to do my KISS approach to editing then so much the better. Cropping, noise reduction/control, contrast, levels, dynamic range 'control', capture sharpening, output sharpening (I really like PS Smart Sharpening
), lens corrections.......
Though overcooked fancy filters are of limited interest, that is why On1 software has never had much appeal because IMO that seems to be it's main selling point!
I suppose it is just a case of finding one with a good to great raw processor with the controls I list above.......plus any that make sense to bring out the best of the latent image such 'old style' dodging & burning
but sticking with LR for the DAM it gives me.
