And once again down the rabbit hole... the author presents a superficially compelling story, but much of it rests upon a vague accusation that Lr has terrible image quality. No specific example is given, no evidence is offered. This undermines the whole argument. It seems easy to forget that Lr and Camera Raw in particular were designed and are still maintained by a number of the absolute best practitioners in the field, who, I am sure, take it as a matter of honour to do the very best they can. It‘s easy to get wound up about Adobe corporate strategy, but that is not relevant to the quality of the software development teams.
As for features, really, what else do you want? Development has stalled almost every where, really. There‘s not much more you can usefully do to Raw file that Lr, C1, DxO etc are not already doing. Upstarts like ON1 and Luminar are just doing the same things wrapped up in bright new packaging, and from the sound of it they‘re not doing them all that well. I can understand why for some types of photography C1 has some advantages. Also, if you like drastically underexposing I suppose DxO Prime is attractive. But to my eyes the principal thing these two applications do over Lr - aside from draining your wallet - is hugely pumping up the initial preview to get the wow factor. If I ever use C1, the first thing I do is change the curve to linear... and hey, it looks just like Adobe Standard.
The area which really has potential for improvement is workflow, and Adobe is light years ahead here. Just being able to seamlessly switch from editing a photo in Lr Classic to editing it on my iPad is huge, for me. I have quite a high opinion of Exposure X4, but it has nothing at all to offer in the workflow area, so I‘d be shooting myself in the foot if I switched to it. Certainly Lr could use some serious improvements in masking and local adjustments, but there are workarounds, usually. It could also use some improvements in the DAM, but since it has exactly zero competition in that area, I guess there is no commercial reason to do anything.
And if I‘m coming across as an Lr apologist, well, think again. I‘m actually a bitter and twisted Aperture refugee, so by definition Lr to me is the work of Satan. I‘d love to switch - but I‘ve never seen anything even vaguely approaching a compelling reason to do so.
