When you join this group you will learn all about 3D stereograms, you can share your own stereograms and add links to stereogram related websites. You can view member's stereograms in the Photos and Files section. Most are very well done and many have never been published before.

Stereogram images create the optical illusion of depth when the viewer
allows his or her eyes to focus behind an image (diverge), or focus in front of the image (converge). The slight differences in vertical repetitions of figures, patterns or random dots create the illusion of depth in a 2D image, just as the slight difference in perspective between one's eyes creates the perception of depth with 3D objects and scenes.

Stereograms had been in existence for years before being re-popularized by the creation of computer generated random-dot stereograms (SIRDS). Traditionally, you make a stereo image by taking two photographs of an object or scene rom a slightly different angle (see stereoscopy), but in Single Image Stereograms the image is hidden until the viewer focuses their eyes correctly. The Magic Eye series helped bring stereograms back into favor with the general public.

"Individual email" subscription is highly recommended, thus you will be receiving stereograms as attached files. "Daily digest" and "no email" subscription will not allow you to get the images.
