Learning to use Adobe Photoshop is similar to learning to play an electric guitar—with a little instruction and a little practice, you can create some very pleasant art. Or, if you're really motivated, you can lock yourself in a closet with it for 12 years and emerge playing some amazing "licks." Most of us fall somewhere in between, and all of us have more to learn.
But the thing is, although few people are frightened by a guitar, many people find Photoshop intimidating. That's what is so great about Ben Willmore, the author of this book: He takes away your fear.
