All the images you see above have been edited/produced using Affinity Photo. I work for Serif Software (who make the Affinity applications) as the Affinity Photo product expert and “look after” the application in terms of tutorials, demos, workflows and general usage.
I produce and maintain a series of resources for Affinity Photo, including various macros (automated actions) that extend the range of functionality and make users' lives easier. Most of these are free, and for some resources I charge a small fee due to hosting costs. You can download them from the main resources page.
