Stereogram is an optical illusion based on the ability of the eyes to capture images from different points of view. These different perspectives are captured in such a way by the brain, which seems to be a three-dimensional image.
Stereograms have been made for years, superimposing two photographs taken from slightly different angles. However, they have now become popular, thanks to the RDS (Stereogram of random points) created with computer programs.
To see a stereogram, the main thing is to understand the expected result. The idea is to blur the view of the image, so that both perspectives are captured. Some recommend looking at infinity, that is, fixing the view on a distant object and without blurring, try to look at the image. Others prefer to fix their eyes on a finger while slowly approaching the image, or try to observe the reflection of the image in a glass; Depends on each one and their visual condition.
Includes: 60 stereograms
