I was listening to people on the radio complaining about the prevalence of photoshopped pictures on internet dating sites this morning, and found this nice 3 minute photoshop demonstration. It really shows what you can do if you know what you're doing. Not the best thing to look at if you are at work - no nudity, but some risque attire.
Seen it? Good, now if you know anybody really good at photoshop, send them my way so he or she can make me look like Brad Pitt before I sign up for any online dating services.
