The simplest way to view the stereo pairs is to go cross-eyed until the two images appear to overlap and a third image seems to exist between them. This is easiest when the pictures are either small, or viewed from far away. If you ever looked at “Magic Eye” books in the 90s, it is a very similar process! Many people cannot (or will not try to) use this technique. In this case, you can use an set of inexpensive 3d viewers which are easily found on eBay. If viewing these images causes any discomfort at all, please do not attempt it.
