Since a young age I have had an interest in stereo photography so have included a variety of subjects here.
The images are either in the form of X-eye stereo pairs, these give the best 3D image, or Red-Cyan "Anaglyphs".
To view a X-eye image you will need to train your eyes to the cross-eye method where you intentionally squint your eyes to merge the two images. It requires a bit of practice but worth it !
To view the Anaglyph galleries you will need to use Red-Cyan glasses but the effect depends on how well matched your actual red-cyan glasses are to the colour balance of the screen you are viewing.
Most recent, and probably the most unusual, are the stereo views of the moon: more explanation in the actual Lunar galleries.
