With Affinity Photo the editing for portraiture is excellent. Have a look at Tube instructions for basic face editing - not a masterwork but good indicator of what is possible. High&Low frequency layers, Liquid, De noiseing etc. etc.
My ONLY problem with Affinity has been the rather slow implementation of Fuji Raf file handling efficiency but even that looks like it is being sorted with the 1.7 release.
I am sure that if (G*D forbid) I ever went back to work that Affinity would remain my Go To image editing software.
nb:- not an employee or whatever.
Oh and of course AP has a iPad version (full editing - not mini version)
