I am editing a B&W 1920s album of First World War pictures of my grandfather, who was a pilot in the Royal Flying Corps. The pictures are interesting: in cockpit; crashes; French allies; German prisoners etc. I have scanned them in on a flat-bed scanner. Is there likely to be any qualitative difference between the edits I do on Photoshop Elements 11 on Mac and Affinity Photo? Frankly, I just doubt it. The amount of data in these prints that is very limited, sadly (I only have a few negatives.) As I really know PE and I am just starting with Affinity Photos, maybe I would save myself some grief and just use PE. My aim is to show them all to the Imperial War Museum and if they want the album they can have it.
