Retouching For Smooth Skin

OK you're probably wondering why I would place a tutorial about how to smooth skin on my site, which I call Shooting Outside. But I can easily justify this, (tongue in cheek) as this was shot, yup, outside. No matter. The important thing is here's how to smooth out skin in nearly any shot if you are using, and here's the key, Photoshop CS3. Take a look & let us know how you like it. Would it be worth spending $650?
