If they are viewed cross-eyed, by focusing on a point in front of the image, then the effect will be reversed. The stereograms above are designed to be viewed wall-eyed, by allowing your vision to focus on a point behind the image. Cross-view stereograms are also fun.Īutostereograms can be viewed wall-eyed or cross-eyed. Another type of stereogram consists of two images taken from slightly different angles, viewed through a stereoscope so that each eye sees only one image. The stereograms on this page are autostereograms, which means that they are contained in a single image and do not require a stereoscope to view. The 3D effect is created when your eyes combine the two images. The image above is one type of random dot stereogram, which takes advantage of a chaotic background to allow the mask image to be repeated while still blending in. Notice the illusion of depth, with certain parts of the trike in the foreground and certain parts in the background. Hold the image below close to your eyes and allow your eyes to unfocus slightly until an image pops into view.ĭo you see the tricycle? Once it is in view, you can even move your head slightly to see the 3D image seem to hover in place.

The Magic Eye series of books popularized stereograms in the 1990s. This type of stereogram is made simply by repeating images of different widths. (If you cross your eyes instead of allowing them to unfocus, then the gorillas will be in the foreground instead.) If you then slowly move your face further away from the image, the 3D effect is quite vivid. If you hold the image close and allow your eyes to unfocus, the rows of animals should appear to hover at three different depths, with the leopards in the foreground, the parrots in the middle ground, and the gorillas in the background. Look beyond the image (try focusing on a imagined dot behind the image)Īt some moment, you will gain insight and start seeing the hidden object.Stereograms allow you to see a three-dimensional shape while looking at a two-dimensional image.Sit in front of the image about 30 to 40 cm part.Repeat it a few times to get use to the eye coordination Bring your attention back to your fingers and watch the ghostly finger disappear.Keep relaxing your glaze and maintain image of the ghostly finger there.Notice a ghostly finger appearing magically in between your index fingers. Now focus your attention on a distance object.Bring the fingers in alignment pointing and touching.Hold your index fingers right in front of you at around.To prep yourself for the investigation, let's do some warm up first with the following steps. The following activity allows you to experience divergent eye teaming. The feeling of discovering what is behind the scene is too intoxicating.
I cannot have enough of stereograms myself. Hidden 3D object will appear in the picture itself! When you focus behind (look into) the image and diverge your eyes, a Present wrapper without any special meaning to it.īut once you start looking at the image in a special way, magic happens. Like painting made up of repeated patterns. The reason being that, to see the illusion, one needs to use certain eye coordination skill (visual divergence) which is unavailable to people with visual impairments affecting one or both eyes.įor the others who are more fortunate, while some of them can easily see the 3D image hidden in a stereogram, most of us (including myself) have to train our eyes to see it. The first thing you need to know is that, sadly, not everybody can see the 3D illusion in a stereogram. In this article, I am going to focus on the most simple stereogram, autostereograms, which is created from models that repeat itself horizontally and requires divergent viewing.
Today, there are many types of stereograms. Stereoscope is a viewing device that allows a person to see 3D image from 2 slightly different 2D photographs or drawings.
