Stereogram Training Gallery
Stereogram training gallery is perfect start for stereograms beginners and for everybody who don’t see stereograms or who never see a hidden 3D stereogram illusion.
Here is basic training set of strereograms for beginners. How to train to see hidden 3D images?
First is good visible 3D string. Click on image and try to recognize 3D depth of image.
Click on image to display stereogram – don’t zoom displayed image
Some people cannot see hidden stereogram images because of health limitations – dominant eye, lazy eye, exophoria and exotropia.
There is recommended to adjust distance from stereogram image – try different distances to avoid limitations of your eyes.
How to view Stereograms?
Most of Stereograms are diverging or parallel. It means that focus point is behind the monitor or printed stereogram. There are many ways how to train:
- Method 1 focus behind target – place something behind monitor 30cm/feet and you can see it. Focus your eyes on it for few seconds and swing your eye focus to stereogram. If you don’t see depth in stereogram swing your eyes and focus behind monitor. Repeat it again and try stay focused behind monitor – 2 second behind monitor, 1 second on stereogram.
- Method 2 de-focus your eyes – Move your head very near to stereogram image, just few centimeters/inches. Your eyes can’t focus for this distance. Try stay focused to distance and slowly move your head back. In distance about 30 cm/11 inches you can start to see depth of stereogram.
- Hint – don’t resize/zoom stereogram image, try to see it in original size
How to create stereograms for beginners?
You can use Stereogram Explorer to create easy visible stereograms for beginners
Recommend stereogram configuration:
- Stereogram type – diverging/parallel SIS type (textured stereograms)
- Content – use simple 3D object or 3D depth map without small details and without large plain shapes, try to avoid content with near min 3D depth and max 3D depth
- 3D Depth – use medium size of 3D depth, small depth is not the best for beginners, high depth is recommended for trained eyes and may burdens the eyes
- Separation – use separation in average values, think of the medium on which the image will be displayed (display or paper), stereogram printed on paper in high resolution need different separation value as displayed on monitor display
- Texture – use high contract texture with small elements, don’t forget about color-blind people
- Antialiasing (Stereogram Explorer specific) – enable antialiasing (from 4 to 8)
