Crossed 3D Photos

The three photos in this post are crossed 3D pictures taken with a 3D camera that uses two lenses instead of just one.  The two lenses give a slightly different perspective on the scene, just as our two eyes see everything a bit differently.  When the brain combines the two images a very nice 3D sensation is produced.

As I mentioned, these photos are "crossed 3D."  What this means is that the proper viewing technique is for the right eye to view the left image and the left eye to view the right image.  To accomplish this, first pretend to be looking at something just in front of your nose.  As you do so each image will double.  In the middle the images overlap.  By making them overlap perfectly, and keeping them overlapped as you adjust your focus, you can view the 3D effect.

The first photo is on my deck, looking out toward Burrows Island in Puget Sound.  The small spot just above and to the right of center is a Paddle-tailed Darner (Mr. Happy-Face).

Betsy on the south rim of the Grand Canyon.

Our lunch spot at the Boyce Thompson Arboretum, near Mesa, AZ.  We've hiked on the hillside in the background many times.  In the spring of 2011 a wildfire burned on the hill right down to the trail.  Fortunately, it didn't cross the trail or enter the main grounds of the Arboretum.
