7. Zoom out so that the combined image is just a few tens of millimetres wide. Using the free-viewing technique described below, try to view the stereo pair in 3D. If you can’t see the image, check that both images are correctly positioned. Once you can see the scene in 3D, move on to the next step.
8. You’ll probably want to make prints of your stereo pairs. Remember that the larger the image, the harder it will be to free view it in 3D. Unless you use a stereoscope, you can’t just print at any size as you would with an ordinary photograph. Make a few test prints at various sizes and try them out on your friends.
9. If you find free viewing difficult, try an anaglyph. Just about anyone can view in 3D using special glasses with coloured lenses. Install Anaglyph Maker, then click Load Left Image and browse to it. Open the righthand image in the same way by clicking Load Right Image.
10. Depending on the type of 3D viewing glasses you have, select either the Anaglyph Gray (Red-Cyan), Anaglyph Red-Green, or Anaglyph Red-Blue button before clicking Make 3D Image. A version of your photo with odd colours and fringes around objects will appear in the preview area.
