This is a set of example .afphoto documents to demonstrate non-destructive editing workflows in Affinity Photo.
Please note that you will require Affinity Photo 2.2.0 or later (updates for V2 are free, so users do not need to be financially restricted to a previous version).
Each document will allow you to fully explore the non-destructive layer stack—you can hide, show and manipulate layers and see how they all contribute to the final result.
I hope they give you some practical ideas about how to approach your own editing within Affinity Photo!
