Thanks Doug.
I’ve tried two so far without much ease manipulating imported images.
The first one I tried was ArtRage. I was able to import an image easily enough but manipulating the image I found to be very clunky.
Next I tried, Clip Studio Paint. Better, I’m making much quicker progress importing and manipulating images but still not that intuitive in my opinion. For example, I select the Marquee tool but once I’d drawn out an area ready to crop it I can’t find a way to re-size the marked out area if I need to.
Any one had success with these tools; that is, should I persist with either of them? Or anything better anyone could recommend?
