Stereo Pictures (3D) – 2nd Set
Here are a number of stereo pictures, taken with a home-made stereo camera. It is essentially a holder for two cameras, with a handle, and a trigger to fire both cameras at the same time.
Here is a picture of Deborah, holding the camera, with an eruption of Great Fountain Geyser (in Yellowstone National Park) in the background:
The pictures are arranged in pairs to be viewed using the cross-eyed method. You can learn that method (with a lot of trying) as follows:
Hold up you thumb in front of the pictures, and look at the end of your thumb (with the pictures blurry in the background).
Still looking at your thumb, move it closer to you, or farther away, so that the two pairs of blurry pictures in the background merge the inner pictures to where they are super-imposed, so there are 3 blurry pictures in the background.
Try to look at the middle blurry picture (it takes a lot of trying to get your eyes to focus 'far' when they are pointed 'near').
Keep trying. It took me a long time to finally learn to do it. Once you learn how, it will be easy to look at them, and you won't even need to use your thumb.
