A comprehensive look at everything there is to learn in Photoshop. Or at least as much as can be covered in 10 minutes. If you've never used Photoshop before, this is the place to start with guidance to what free resource to move on to next.
You think you know everything about Photoshop? You don't. Unless you watch this series. And then you will. (Until I make a new series. And then you won't. Or something.) Seriously - some amazing techniques on selections, masks, channels, and other things that sound really boring when I type them out here. But are far more interesting in video form. For real. They are. Trust me. This is way better than the Crash Course I made.
