Stereo Pair Viewing Instructions

When overlapping stereo pairs without special glasses, you can obtain the 3D effect by crossing your eyes. Sit in front of your monitor, with the image directly in front of you, at about arm’s length. Keep your head level horizontally--tilting your head will prevent you from merging the images. While keeping the stereo pair of images in the centre of your vision, slowly cross your eyes. It can help to hold a pen in front of you and look at the tip with the stereo pair in the background. Gradually cross your eyes more and more until the images overlap (if using a pen to assist, start it close to the monitor and move it towards your nose). Try and hold the centre image together – it is possible to “lock” it in place and see it as one image. The “locked” centre image should appear in 3D!
