To start learning free-viewing, first choose an image pair. Place a finger about 6 inches in front of you, between the center of the image pair and your eyes. Make sure your line of sight is directly in front and perpendicular to the center of the image pair (Only one person can view at any one time). Then look at the tip of the finger (do not look at the image pair). With your eyes focussed on the finger tip for about 10 sec, quickly look at the third image, which should appear at the center, between the image pair. You should see a 3D image in full colour. If you do not see the 3D image, repeat the same steps as above, varying the distances slightly, until you can see it. Although it is so easy for most people, not all can get it right the first time. Once this technique is acquired and practised often, one can use it to view 3D pairs instantly without need for the aid of the finger aid. As not many people have acquired this simple skill yet, you will be able to feel good about it. Believe me, it's easier than riding a bicycle!
