Trying to master the Adobe Creative Cloud suite of applications is a full time project for probably the rest of your life. This is the suite that has Photoshop, Illustrator, Lightroom, Dreamweaver and 19 more! You may not live long enough to just learn Photoshop. Even after you think you know something, you have to use that knowledge frequently (like, every day) or you’re going to forget it.
There are hundreds if not thousands of tutorials out there to help you along your path, but it you don’t take copious notes as you learn this stuff you’re going to be continually searching the Internet (how do I make an image show through text?).
Not to confuse you, but I’m going to explain a few things I’ve learned along the way that I found useful. I’ll also mention some good tutorials I’ve found.
I probably won’t do much with Dreamweaver because, well, who uses Dreamweaver any more? But Photoshop, Illustrator, Lightroom? I’ll be all over them.
