I don't own Affinity Photo, and I assume the photo editing tools in Publisher are for people like me who want to edit pictures all in one program. There is a button marked 'Edit Image' which leads me to the tools. From then on I'm stuck, as there's no Help article on 'Edit Image', and when I do edit the image it's not clear how to get my alterations into the original image which stays the same. If I close and Save the edited image, that seems to work, but is that what I'm meant to do? It seems a bit drastic to have to close the image corrections in order to get them onto the original image.
Maybe the answer is obvious, but it would help to have a Help article on 'Edit Image'.
Thanks for the brilliant tutorial videos.
