Well yes and no. You'd be cutting and pasting a picture of you ... on top of a picture of you. So you'd take the photo exactly as you want it, adjust the focus to focus on you, then take the second photo moments later. Then in photoshop you'd just be combining the best of both photos, or at least the best focusing.
That'd be by far the easiest way to take the shot. Photoshop is a valuable tool for photographers in the digital age, what would've been done in the darkroom is now done on the keyboard. It's still photography, only you use different tools. The problem comes when ametuers (for the most part) go over board making digital creations that are so overly edited it makes us cring. But it doesn't make the tool the problem, just those who overly use / abuse it.
The editing jonmikal described falls into acceptable editing in my books. At least the way I understood it.
