I tried opening both DNG format RAW files (as produced by my Pentax DSLR) and JPG files, and tried to do the basic things I would often do in Photoshop Elements 7. The interface, and its complexity, was very frustrating (Personae?). What I really wanted to try was the automated removal of green/mauve colour fringes on high contrast areas of the image, and on the one occasion when I got this to work the results did not appear any better than I can do 'manually' in PE7 by selecting specific areas of the image and using 'replace colour', although it takes a little longer to do. I also tried to correct a distorted image (sloping horizon and converging verticals), which takes a few moments to do in PE7, and never managed to make it work. The free trial period is now over, and I have uninstalled the Affinity software. Thank you for you help: this is a clear example of having a friend who is already familiar with the software and can show you some things would be really helpful, since Affinity can't be bothered to produce a user manual.
