3D Digital Images Made Easy
by Dave Johnson
Thanks to last month`s Super Bowl commercials and a special episode of the geek-action show Chuck, everyone has been talking about 3D recently. I even got a set of awkward 3D glasses from the local supermarket to see what all the fuss was about.
Frankly, I found it all a little underwhelming. That inspired me to have some fun with the third dimension with my own photos. As you`ll see this week, it`s not too hard to make your own photos look 3D using some clever composition and a free animation program.
The Science of 3D
Why do things look 3D to begin with? The effect relies on the fact that our eyes are separated by a few inches, so they see everything from two slightly different angles. The result is a phenomenon known as parallax–the relative position of close objects varies more to your eyes than the relative position of more distant objects.
With a single lens, there`s no way to capture the effect of parallax in one photo. But what if you had two cameras, or took the same photo twice, moving the camera between shots?
