Photoshop has grown and changed over the last two decades, becoming something new and unexpected. That’s great: it means new functionality and (in theory) better performance. But if, like my dad, you’ve been using the app from the beginning, when it was a tiny village that did one thing and did it well, you might be suspicious of all this change. Or at least wonder what it’s good for. Photoshop today seems basically feature complete, and totally unassailable. It's more than just the best professional image editing app: it's kind of the only professional image editing app. It’s the city that, to do your job, you have to live in.
