I've been using Affinity Photo since October 2017 for editing images on the iMac. I used to use Adobe's Photoshop Elements, but the version I was using had problems on the latest version of the Mac operating system and I didn't want to move to a subscription model that Adobe now favour. I'm not a professional photographer, or even a serious amateur one. Affinity Photo also has an iPad version which is attractive.

So far Affinity Photo has done what I needed to do, it's a little complicated in places.
