I am not one of the “experienced people” for photo editing, but I have found the Photo Workbook really helpful when trying to do some of the things that it describes. One can try something until it works. The extensive library of Affinity Photo tutorials is excellent and covers so much. For me sometimes - particularly when I was just getting started and didn’t have a clue about the workspace - they go too fast to grasp what is going on (which panel, which tool, “where is invert?”) until we have galloped much farther through the session. But there is always “repeat.” The forums are superb. So many really nice people who can figure anything out!! I think that learning the workspace (layers, filters, swatches, styles, assets, brushes, etc.) is the key. For me the book has been really helpful because “fast forward” just means turning the page.
