Stereoscopic photography . . . . .

Ok, where’s he going with this one?  ■  Stereoscopic photographs are 2 photos taken of the same scene, but taken from slightly different angles.  You’re probably familiar with the old stereographic viewers that had a circular card with photos on it that you inserted into the handheld viewer and voila – a photo that looked 3D.  ■  To view my homemade 3D photo click on it to view it in a larger size – then you’ll have to sort of stare at it and cross your eyes until it forms a 3rd image between the two.  That image will be in 3D.  This could take some practice, but you’ll get it eventually.  ■  When I was in college I was a geography major, geology minor.  One of my courses was a class in air photography.  In order to see things in 3D, two photos of each image were taken at the same time a few degrees apart.  Put next to each other you could discern a 3 dimensional image of the area photographed.  While we used special “glasses” to make the viewing easier, most of us in the class were able to view the photos in 3D without their aid.  ■  So, go ahead and give it a shot.  ■
