Are any of them able to properly read a .PSD file? In particular, I found that Krita was able to load my files, but all of my colour correction & adjustment layers were gone.
And GIMP... ugh. Trash software. Sorry... but it completely lacks the ability to do non-destructive editing - a feature which was proposed ***15 YEARS AGO***
Paint.NET is good, but it isn't a photoshop replacement. It is a MS Paint replacement.
At least there's RawTherapee for raw edits.
