It’s time to dust off your old 3-D glasses – you know, the ones with the red and green lenses! Engadget has a tutorial that will show you How-To Make 3-D photos. If you have a PC, the article show you how to create the image using a freeware utility. If you happen to have a Mac, the process is described using Photoshop. I think this is a lot more than a legacy novelty–transforming visuals from a 2-D screen into a 3-D experience has had people willing to put on funky glasses ever since the 1950s, and I think it’s still a small price to pay! Any rate, you don’t see articles like this every day from Engadget so go take a look.
