Hi Jonh, thank you very much for your help. That is what you will need, a file next to the Raw with the encoding of the settings in Raw to be able to resume them again with the Raw file. I have done several different tests, also revealing the Raw and going to "Person photo" saving the file instead of exporting. But later, when you open that .affinity file, the photo opens in "Persona photo". It is a pity that Affinity does not save an extended file with Raw encoding to resume work later and that the changes are not lost.
Even so I am very surprised with the capabilities of Affinity Photo, being able to edit the Raw in this application is great.
One last thing, to clarify the workflow with Raw. We could say that when developing the Raw and going to the editor of "Persona Photo" is a process of "no return", right?. If we wanted to edit that Raw file another time, we would have to start over at "Persona Develope", right?
I apologize for the length of the text and for my way of expressing myself in English
Thank you very much again.
