Both the photographic industry and the printing industry in the USA use Inches as the only way to express measurements.
You can do this in Photoshop, and it keeps me going back for that feature alone.
I really like the Affinity suite, and would like to use it exclusively. But, when I sit down to edit a few hundred photos, and have to individually set every one to inches, it is just too involved and too likely to be missed only to be discovered at the press proof. (after spending a LOT of money and time)
How many other Photographers are in my place - wishing for that one modification?
Affinity allows customizing almost everything, even to make it look and work like Photoshop, but not this!
WHY?
