While the show has, sadly, been cancelled, hours of new "The Lab with Leo Laporte" episodes are scheduled for broadcast and a few of my favorite segments have yet to be seen.

One such segment is the Invisible People Photoshop tutorial. There are several tutorials out there that will show you how to totally remove an unwanted person from a photograph; that's not what this one does. The Invisible People Photoshop tutorial will show you how to "erase" the person and leave his clothes behind--as if he were invisible!

Why would you want to do such a thing? For starters, it's an excellent challenge and a great way to strengthen your Photoshop skills. But, check out FilmWise's Invisibles Quizzes to see this technique put to mind-bending good use. If you get good at this effect, the folks at FilmWise might even use one of your cinematic disappearing acts in a possible upcoming "User-Created Invisibles Quiz."
