If you’re on macOS and just want a good and convenient image editor, I warmly recommend Acorn. The Muellers (owners of Flying Meat Software) have put a lot of effort to make it feel like a really solid Mac application. The price is good and from time to time they offer discounts. The whole experience reminds me of using good old Paintshop Pro back in the late 90s (^_^) Other options are Affinity Photo from Serif Ltd…
