I came across this fantastic Affinity Photo editor, when i was searching for an alternative to photoshop.
The Price is low compared to adobes yearly subscription to access their software.
And its almost just as good. it takes some time to get the touch of the different shortcut system, but overall its something i will recommend highly.
Affinity have delivered af version of adobe creative suite package, with Photo, designer and Publisher software in 3 different programs.
They each comes with a price of around 60 €. for life. No subscription
Check out they webpage for more info.
Also there is a lot of tutorials on their own site
And of course also on Youtube:
