The image on the left is a picture I found online called "Beavis."
I do not know if there is actually a guy walking around looking like this, but I found the picture here. I am not sure of the accuracy of the article, though.
The image on the right is the same image, enhanced with Adobe Photoshop CS4. The only deviation from the methods reviewed in class is my addition of an extra layer containing only the face from the chin up (ears excluded) to add a different type of blur. From there, I adjusted the opacity of the two blurred layers until the guy did not appear to be plastic. To some, he still might. Practice makes perfect-ish.
