Hi there,

I was wondering does a person need to be able to decode a stereogram in order to succeed the focus while photo reading.

Namely, I visited Wikipedia page http://en.wikipedia.org/wiki/Image:Stere...ula,_Russia.jpg and there I am able to get the third picture from those two (something similar should I get when I hold the book opened, that cylinder, right?), but later on I tried with other stereograms on the net i.e. http://www.eyetricks.com/3dstereo.htm and wasn't able to see anything.

Do I need to see stereograms and will I with that improve my focus ability?

Thanks a lot.
Regards
