It's a must learn. Don't listen to any of these outsourcing crazies who think they're Tim Ferriss.
Imagine getting a logo and you just want to change one or two little things. You know photoshop means you can do it, you don't means you get to wait 24-48 hours for your design guy to do it or 5 minutes for yourself.
Time is money! Learn some photoshop, at least the basics!
