Page "Stereogram" Paragraph 10

: According to Magic Eye, a maker of autostereograms, " most people prefer the diverging method ".

However, with normal stereograms, this imposes a limit on the size of the image, since there is a limit to how much the eyes diverge ; images created for the cross-eyed method can be larger.

If a stereogram is viewed with the wrong method, the depth information is seen ' reversed '; points intended to be in the background appear in the foreground and vice versa.
