Open the image in an image manipulation program such as Photoshop or Gimp. The easiest thing to do is take a picture of a TV screen when it is not tuned to a channel. To create a random dot stereogram like this, first you will need a picture of random dots. At that point, you should see a 3D image appear below the dot.Ĭan you see the skull? Do you find it harder or easier to see than the tricycle? Cross your eyes so that each red dot becomes two dots, and then allow the dots closest to the center to overlap and lock into a single red dot. The red dots are included to help you lock the image into place.

Unlike the images above, this stereogram is designed to be viewed cross-eyed, and you will probably not want the image as close to your eyes.

Here, I will show you how to create the stereogram below.

However, it is also possible to create simple random dot stereograms using image manipulation software such as Photoshop or Gimp. Generally, a stereogram that shows different levels of depth will require software that can determine the location of each pixel using a depth map. The tricycle and airplane stereograms above were created using. Stereograms of moving images are also possible. So instead of seeing a 3D tricycle or airplane, you will see a tricycle or airplane-shaped hole. 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. Stereograms allow you to see a three-dimensional shape while looking at a two-dimensional image.
