Photoshop is a workhorse of which the first versions were released as early as the mid-eighties of the past century. Affinity Photo is brand new. So, would it be fair to compare them? If there would be any logic in software development, I’d answer that question with a “No”. But there isn’t — logic, I mean. Affinity Photo may well blow Photoshop out of the water. It’s faster, has no historically grown rubbish the developer needs to keep in there and is just plain powerful. And best of all: its licence model is customer-friendly.
