HOW TO SEE THE PHOTOS IN 3D

• The picture pairs are best viewed in bright light as this brings out the detail and 3D-depth.
• If you wear spectacles for reading, wear them now.
• Hold the book level in front of you with both hands. Make sure the page with the stereo photo is completely flat. Now look through the lenses. Your eyes should fuse the two photographs into one 3D image.
• Most people can do this quickly, and once you have seen the three-dimensional effect you’ll have it mastered.
• To fuse the two images, it may help if you move the whole book slowly away from you until you have a 3D picture.
• You can also tilt the lens flap and the picture pairs towards you and away from you until the two images merge into one 3D view.
• Don’t give up if you don’t see the 3D-effect immediately. Relax your eyes, look at a distant object beyond the book and then look through the lenses again with your eyes still focused in the distance.
• Take your time; you will love the 3D experience once you have seen it.

In addition to the 49 stereographs, 3D Expo 1862 contains 51 large mono photographs for enjoyment without stereopsis.
