I'd like to make it clear that I'm extremely satisfied with Affinity Photo, but I personally expect the developers to develop the software in the spirit of Photoshop, in particular for "automatic" selections such as "sky, background, object", etc., so as to save time in Post Production.
In any case, thank you once again to the engineers, who have succeeded in making an extremely powerful piece of software, at a very aggressive price.
Affinity Photo is much more precise, and more pleasant to use, if I compare it to DXO and ON1.
But this is just my personal perception of Affinity Photo.
