Introduction: How to View Stereo Graphic Images

About: Have 30+ years of experiences as a Mixed Signal IC Design Engineer.
Stereo graphic images can be viewed as though looking to the horizon through a window. If the two images are spaced at the right distance, the 3 Dimensional image will come into focus when the eyes are most relaxed.

Step 1: Start With the Images

Start off staring at the two images.

Step 2: Relax Eyes

Now completely relax your eyes and go out of focus (focus on the horizon).
Tilt your head until you see three images line up like so.

Step 3: Focus on the Center Image.

Now focus on the details inside the center image.
Tilt your head if needed and view image as though looking through a window.
Relax and the center window will come into 3D .

Step 4: May Need to Scale the Images

The 3D viewing is easiest when the width of one picture equals the distance between the eyes. Sometimes a image may need to be scaled in size to do this.
