Skylums Lumniar promotes itself as being a lightroom replacement-
But is it really?
First the big one Lumniar currently has no digital asset management features period!
They are promising some features later in 2018 however a promise is not worth much and we will have to wait to see how those features pan out in reality, given this is an important feature for me this pretty much rules Luminar out of contention till these features appear.
Lumniar is very much a preset driven application if you prefer to try different canned presets to find a starting point for your images then this may appeal.
Personally I prefer a more adjustment driven interface, even the basic adjustments have to be added to your image as a preset and then tweaked to your preference I make no bone's about this I don't particularly like this style of interface and method of working. However it seems pretty powerful and there are many useful tools you can use gradient masks etc and with some practice it may become more intuitive to use.
Unlike Lightroom Luminar has no panorama or hdr functionality
The application also seems a bit buggy and has crashed several times already this will be interesting to revisit later when the D.A.M features have been added but as it stand now it isn't in the running.
