How do you view a stereogram?
Viewing Techniques: Most Stereogram pictures are usually generated so that if you look at (converge your eyes on) a position twice as far away as the picture, and focus on the picture, generally after a few minutes you see a surprising 3D image!
What is a stereogram used for?
Stereogram was originally used to describe as a pair of 2D images used in stereoscope to present a 3D image to viewers. The “auto” in autostereogram describes an image that does not require a stereoscope. The term stereogram is now often used interchangeably with autostereogram.
How does a stereogram work?
HOW DOES IT WORK? A stereogram is an image which, when viewed with two eyes, produces the illusion of depth perception. These versions were made on computers, and use subtle changes in a repeating pattern to combine depth information for both eyes into one single image.
Are 3D pictures bad for your eyes?
Actually, no. The headaches and nausea are basically the result of stress from your eyes and brain having to work differently to process images. As far as your eyesight goes, there is no evidence suggesting that 3D movies cause long-term vision problems.

No problem. Use a printed image rather than the monitor. Start with bringing the stereogram image really close to your eyes (touching your nose). Slowly move the image away from you while keeping your eyes off focus. At some point , you should be able to see the 3D image.
Is it possible to make a stereogram using Photoshop?
Generally, a stereogram that shows different levels of depth will require software that can determine the location of each pixel using a depth map. However, it is also possible to create simple random dot stereograms using image manipulation software such as Photoshop or Gimp. Here, I will show you how to create the stereogram below.
