This is my first real attempt at taking a stereo photo, and I think it worked. To view this in stereo, click on the above to go to the full-size version (you can try viewing it with the photo above too, it just won't be as detailed).
Then relax your eye muscles so that the two photos begin to meld into one. It's a little like crossing your eyes, but nowhere near as much work; what you're doing is letting your eyes go out of focus momentarily.
When you begin to see a third, melded photo between the two original ones, bring your eyes softly into focus on that third center photo. You'll know you've done it when the joe pye pops right out of the screen! You will be able to easily move your focus around inside the third photo and explore the grasses and other plants in different depths of field.
